1. INTRODUCTION

Accurate knowledge of the condition of oil-filled equipment is of paramount importance to electrical utilities. Dissolved Gas Analysis (DGA) has been essential in this area for many years, allowing faults to be detected in their early stages, costly outages to be avoided and assets to be optimized. The TRANSPORT X represents a new generation of test equipment for DGA in equipment oil, allowing accurate, rapid, reliable results in the field. To ensure optimum performance of the TRANSPORT X it is important to read this manual fully before using the equipment.

3. SYSTEM DESCRIPTION

3.1 TRANSPORT X

The TRANSPORT X (see Figure 1) utilizes photo-acoustic spectroscopy (PAS) to perform extremely high quality DGA analyses, giving measurements of all the fault gases plus moisture. The gases extracted from the oil sample using a highly stable headspace equilibrium extraction method are then measured using infrared photo-acoustic spectroscopy (a semiconductor sensor for hydrogen). The TRANSPORT X can also test gas samples taken from a Buchholz relay (although with reduced accuracy due to a very large dilution factor). The wide dynamic range of measurement of the TRANSPORT X means it is also very suitable for testing tap-changer and circuit breaker oil. The TRANSPORT X is contained within a rugged, impact-resistant, carrying case. Accessories for DGA tests of oil are contained within a separate lightweight case. These include a sample bottle with connections and pipes, and a syringe for extracting a 50-mL oil sample from the equipment and injecting it directly into the bottle (see Section 3.2).



The TRANSPORT X contains an embedded PC and touch screen. The incorporated software contains instructions to guide the user through the operation of the system and algorithms to assist the diagnosis of the electrical equipment. The PC has an internal database that can store over 16,000 records. Communication with external PC’s is possible via USB connections, allowing databases to be downloaded to a laptop or desktop PC and then shared as required.

Figure 1. TRANSPORT X A 2-inch thermal printer is provided, enabling the user to maintain hard copy records of all samples tested on the instrument. The power supply requirements are 115/230 Vac, 50/60 Hz. A System Check Kit is available to allow the user to check the calibration accuracy of the TRANSPORT X (see Section 8). Optional extras are available for sampling of direct gas samples (see Section 7), and also for the forced cooling of oil samples.



3.2 SAMPLE BOTTLE AND CONNECTORS

The sample bottle provided includes a “lid assembly” as shown in Figure 2. Each lid assembly is labelled with unique coefficient parameters. For this reason, the lid assembly is not interchangeable with other TRANSPORT X units unless the parameters have been updated on the unit. The lid assembly incorporates airtight compression fittings and a temperature probe incorporating a capacitance moisture sensor, all of which are to be connected to the top panel of the TRANSPORT X. These gas connectors are of the simple “snap-in” type but they are “polarized” so that only one order of connection of the input and return is possible. Users must ensure that these connections are fully made when using the TRANSPORT X.

Figure 2. Sample Bottle and Lid Assembly

It is recommended to analyze the sample as soon as possible after extraction, so that minimal degradation of the oil sample occurs. However, GE Energy provides a ground glass syringe with the TRANSPORT X that can be used for reliable sample storage for several days, provided it is kept out of direct sunlight and extremes of temperature. It is essential that the sample bottle be kept upright and not be inverted or placed in storage on its side while containing oil to avoid ingress of oil into the pipe work. Dispose of the oil as soon as the sample has been tested to minimize the risk of accidental pipe contamination (see Section 6). Clean the bottle thoroughly after each test with a clean dry cloth or tissue (see Section 6). It is important to ensure there is no residue of oil left in the oil injection port of the lid assembly or the connections valve of the syringe, as this could cause contamination of the next sample to be tested. Expel any oil trapped in these locations using a syringe filled with normal ambient air. This will ensure that no unwanted residue of oil remains from a previous sample. Care should also be taken to prevent any contamination from the syringe and thorough cleaning should be performed after each analysis (see Sections 5 and 6). Two Teflon-coated magnetic stirrers are provided; place one in the bottle before the lid is screwed on during assembly of the pipe work. This magnet is rotated within the bottle during the analysis cycle, and its presence is essential for the accurate operation of the TRANSPORT X. The magnetic stir bar should also be wiped clean after each test. The stir bar can be removed from the oil in the bottle using the retriever stick provided. An in-line Teflon filter is fitted in both the return and inlet gas pipes. Luer lock fittings are used to connect these filters. These fittings allow for quick replacement of the filters at regular intervals or if oil should get into the pipe work by accident, thus blocking the filters. These filters are impervious to oil at operating pressure and function to protect the instrument from oil aerosol, accidental spills and airborne dust. Both these filters must be present at all times; if a spill occurs and oil makes its way

into the gas analysis chamber of the photo-acoustic module, the instrument will require a new spectrometer. It is recommended that the Teflon filters be changed after every 20 samples and the user will be reminded to do this by the TRANSPORT X. If any oil residue is present in the pipes, or the filters appear discolored, then the filters should be replaced before testing the next sample. Clean the pipes by a compressed air blowout if oil is present in the pipes.

3.3 ACCESSORIES KIT

The TRANSPORT X comes complete with a full range of accessories and some replacement spare parts. These include:

1 x 50-mL ground glass syringe

1 x three-way plastic stopcock (for use with syringe)

1 x bottle lid assembly (This must be kept with the unit.)

1 x magnet retriever

1 x quick connection valve (for oil injection from the syringe)

2 x Teflon coated stir bars

8 x replacement Teflon filters

1 x 115/230 V power cable

3 x sample bottles All of the accessories are supplied in a light carry case with protective foam inserts (see Figure 3). Every TRANSPORT X unit is paired with a specific accessory case that shares the serial number as the unit with which it shipped. They should be stored together to avoid the bottle lid assembly being used with another TRANSPORT X.

Figure 3. Accessories Kit

3.4 THERMAL PRINTER

The TRANSPORT X is equipped with an inbuilt 2-inch thermal printer that can provide hard copies of results on-site (see Figure 4). Changing the paper roll is very simple, but care must be taken to ensure

the thermo-sensitive side of the paper is orientated correctly during installation. Lift the lid and place the new roll of paper over the roll holder and then replace the lid in its original position.

Note: If the printouts from the thermal printer begin to show a red tint, it is an indication that a new roll of paper will be needed soon.

Figure 4. Thermal Printer

4. OPERATION

The TRANSPORT X has been designed to provide the user with a reliable device that is easy to use in the field. The embedded PC and touch-screen display step-by-step user instructions, and there is also an Instruction Card inserted in the lid of the case. A syringe and valves are supplied for oil sampling and injection.

Note: Please read carefully and observe the following instructions.

Read and follow the on-screen instructions carefully.

Always use 50-mL samples of oil.

Always use a clean syringe, lid assembly and bottle (see Sections 4.2 and 6).

DO NOT use solvents to clean any of the apparatus or accessories.

Place one magnetic stirrer piece in the bottle for the sample to be analyzed correctly.

Following oil injection the sample bottle must not be moved until the analysis is complete. If the bottle is moved the results will be adversely affected.

When containing oil the sample bottle must be kept upright to avoid ingress of oil into the pipe work of the lid assembly.

Always ensure the pipes’ quick connect fittings are connected correctly and securely, as per instructions.

When removed, the bottle lid assembly should be held upright then cleaned carefully with a cloth or tissue after use and before storage to avoid any ingress of oil into the pipe work (see Section 6).

Always empty the sample bottle waste oil after a test is completed. Also, clean the apparatus after every test (see Section 6).

The Purge time can be increased (maximum 10 minutes) to help prevent carry-over from a heavily gassed sample to the next sample. 10 minutes should be used where available time permits.

Once the TRANSPORT X is unpacked from new, or after storage, the user should run a System Flush operation to help clear the gas paths from potential contamination from any packing material/gas effluents (see Section 4.2).

PC sync port



4.1 TURNING ON/OFF

Where possible the instrument should be powered up 20 minutes prior to the first sample injection to allow it to heat up. Oil sampling can be performed in this time if desired. The instrument can also undergo a system flush during this period if desired. The TRANSPORT X is powered by mains-supplied electricity or a suitable AC supply from a DC inverter. To connect the unit to the mains supply, use the IEC cable supplied with the unit. With the unit connected to the mains, switch the power On using the red power switch at the top right of the front panel. The touch screen will then show the launch of the TRANSPORT X software (there will be up to 20 seconds during which the software will boot) and the Main Menu screen (see Figure 5) will be displayed.

Figure 5. Main Menu Screen To turn the unit Off, press the Turn Off button found at the bottom left of the Main Menu (see Figure 5). The system will then advise when it is ready to be switched off (see Figure 6). Use the red power switch to switch off the mains supply.

Figure 6. “Safe to Switch off Power Supply” Screen Similar to a PC, it is not recommended to turn off the unit directly from the power switch without following the above shutdown procedure.



4.2 PREVENTING CONTAMINATION

The TRANSPORT X is designed to prevent contamination between samples using only simple cleaning techniques for the syringe, jar and lid assembly (see Section 6). For best results:

Clean the syringe thoroughly between each sample with a cloth or tissue (see Section 6).

Clean the bottle and stirrer with a cloth or tissue.

Clean the lid assembly pipes and probes with a cloth or tissue. It is recommended that after first unpacking the unit and whenever time permits, the user should implement a System Flush. This process flushes ambient air through the TRANSPORT X for 20 minutes, and will help clear any potential contamination from packing material/prior samples. This function can also be used to clear the TRANSPORT X of gas after a concentrated gas-in-oil sample e.g. LTC. Details regarding the use of this function are given at Section 4.3.5.2.

4.3 TRANSPORT X OPERATION

The instructions displayed on the touch screen are used to control the operation of the TRANSPORT X. Upon powering-up the screen shows the Main Menu display (see Figure 5). There are five options:

Start New Measurement: see Section 4.3.1.

View Previous Results: see Section 4.3.4.

Turn Off: see Section 4.1.

PC Sync: communicating with PC software – see manual.

Settings: see Section 4.3.5.

4.3.1 Performing a New Measurement

4.3.1.1 Entering Measurement Details Into the Database After selecting Start New Measurement in the Main Menu screen (Figure 5), the user must select the Equipment Type to be analyzed from the options available (see Figure 7). This selection is important for the database and the diagnosis options for the sample.

Figure 7. Equipment Type Screen Highlight the desired option and then press the Next button (the default selection is displayed in red). The TRANSPORT X now requests that the information for the database relating to the Equipment Location and the Equipment Identification (ID) is entered into the unit’s memory. The information required by these two screens is vital as it forms the store and search criteria for all records. If the information is new (i.e. not already stored in the Transport X memory), the unit will use the new information and store it as a new set of records with the appropriate date stamp.



First, the Equipment Location screen is displayed (see Figure 8). If the equipment location already exists in the database from a previous test, then the user can select this from the existing database list displayed on the screen using the Up and Down arrows. Once the correct location is highlighted in the left hand window, press the Next button to move to the Equipment ID screen, which is the next screen in the information/data input process.

Figure 8. Equipment Location Screen If the correct location information does not already exist in the database, then the user has to enter it. To do this the user must first press the Add New… button found in the Equipment Location screen (Figure 8). This action causes the display of the keypad on the touch screen (similar to Figure 10). Enter the Equipment Location details using the keypad. The information stored in the database relating to Equipment Location can also be edited using the Edit… button located in the middle of the screen – highlight the record to be edited using the Up and Down arrows, then press the Edit… button and again the Keypad screen is displayed (similar to Figure 10) to enable the user to edit an existing database record. Once the Equipment Location details are correctly entered into the database, press the OK button (which is now active) at the bottom of the Keypad screen. The Equipment ID screen is then displayed (see Figure 9).

Figure 9. Equipment ID Screen Select from the displayed list the appropriate Equipment Identification details of the equipment that is to be used for the analysis then press the Next button. As in the case for the Equipment Location screen, existing details of a record of the Equipment ID screen can be edited by pressing the Edit…



button. However, if the database contains no information concerning the equipment about to be tested, it will be necessary to add this information to the database for the first time. To add new Equipment Identification information, press the Add New… button. The keypad for entering Equipment Identification details is then displayed on the screen (see Figure 10).

Figure 10. Keypad for Entering Equipment ID Details Add the new Equipment ID details and then press the now active OK button. The Manufacturer screen is then displayed (see Figure 11).

Figure 11. Manufacturer Screen Using the Up and Down arrows, select the appropriate Equipment Manufacturer from the entries in the displayed list, then press the Next button. Alternatively, to add a new manufacturer to the list, press the Add New… button; the keypad is displayed (similar to Figure 10). Enter the new Manufacturer details into the database, press the OK button at the bottom of the keypad and the Manufacturer Model screen is displayed (see Figure 12). As for the Manufacturer screen, choose from the displayed list the appropriate model of the equipment about to be analyzed, or press the Add New… button to add a new model to the database. When the correct model details are either selected or entered into the database, press the Finish button at the bottom of the Manufacturer Model screen or the OK button at the bottom of the Keypad screen. The Equipment ID screen (Figure 9) is again displayed to allow for confirmation of all the details entered up to this point.



Figure 12. Manufacturer Model Screen When the Equipment ID details have been correctly entered into the database, press the OK button at the bottom of the keypad screen. This causes the display of the Equipment Sampling Point screen (see Figure 13).

Figure 13. Equipment Sampling Point Screen The Equipment Sampling Point details are entered into the software following the same procedure as discussed above for Equipment Location and Equipment ID. Typical sampling points may be Top, Bottom, Cooling loop, etc. Once the Equipment Sampling Point details have been correctly entered in the database, the user is required to provide details of the source of the sample that is about to be used for a new measurement. To enter the Sample Source details, select the source from the two options displayed on the Sample Source screen (see Figure 14). The default is Oil Sample, but if the sample is gas from the Buchholz relay, then select Gas Sample. Details regarding the sampling and analysis of gases from gas-collecting (Buchholz) relays are described in Section 7. Press the Next button once the correct option has been selected.



Figure 14. Sample Source Screen At this point, when all the necessary information has been entered into the database, a summary of the New Measurement details is displayed in the Details screen (see Figure 15).

Figure 15. Details Screen The user is required to check and confirm all the information that has been entered into the database before continuing. If any errors are noted in the information displayed on the Details screen, use the Back button to reverse back to the screen in the sequence of screens described above where the incorrect entry has been made. Then correct the information entered into the database at that point. Pressing the Next button on the Details screen causes the display of the Optional Details screen (see Figure 16). This screen provides the user with the option of adding comments to a Comment: field for the sample data. This can be used to record additional information for a particular sample or equipment. If this option is required, press the Set button found at the left of the Comment: field to display the keyboard (similar to Figure 10) for entering comments. Press the OK button at the bottom of the keyboard after typing in any comments. The user also has the option of adding the Oil Sampling Temperature (in degrees Celsius), i.e. the temperature of the oil at the time it was sampled as displayed by the transformer temperature gauge or another temperature measurement option. This is used to calculate the % Relative Saturation (%RS) of the sample. If the temperature is not added then the results will not include a %RS figure. To enter the oil temperature, press the Set button found at the left of the Extraction Temperature: field to display the keyboard (similar to Figure 10) for making the temperature entry. Press the OK button at the bottom of the keyboard when the oil temperature has been entered.



Figure 16. Optional Details Screen After all the sample information has been selected or entered, the software guides the user through the testing process. Press the Next button to begin the testing process.

4.3.1.2 Readying the TRANSPORT X for Making a Test While the user is entering the new Measurement Details into the database (Section 4.3.1.1), in the background the TRANSPORT X is undertaking a process of system venting in preparation for taking a new measurement.

Note: Venting occurs only upon the initial start-up of the TRANSPORT X.

Progress in performing the system venting is shown in the Venting System Progress screen (see Figure 17), which will be observed if the first set of new Measurement Details are all entered before the venting process has completed.

Figure 17. Venting System Progress Screen It is a requirement that a clean dry bottle be used for each test. Figure 18 shows the initial instruction screen for the testing process – the Install Bottle Instructions screen. Follow the on-screen instructions and connect the sample bottle to the TRANSPORT X. Press the Next button to proceed with the testing process.



Figure 18. Install Bottle Instructions Screen If the temperature probe is not properly connected, the warning window shown in Figure 19 is displayed. If this occurs, confirm correct connection of the temperature probe, then press the OK button to proceed with the testing.

Figure 19. Bottle Installation Error Message If the bottle temperature connection is in order, the Purging Time window (see Figure 20) is displayed. The unit prepares for the oil sample by first “purging” with ambient air, and then by automatically taking a zero reference measurement. The user selects the required Purging Time, typically between 5 and 10 minutes. The default is 5 minutes, but longer purges can help eliminate contamination from previous samples which were heavily gassed, for example from Tap Changer oil samples.



Figure 20. Purging Time Window Progress in purging the unit is shown in the Purging Progress screen (see Figure 21).

Note: If 5 minutes is selected, the actual time is approximately 5 minutes and 40 seconds as this is a default minimum. If 6 minutes is selected, the actual time 6 minutes.

Figure 21. Purging Progress Screen When the purging is completed, the unit automatically calculates the gas concentrations in the air of the TRANSPORT X / dry sample bottle combination in order to provide a zero reference for sample measurements using the selected sample bottle. The Progress screen is shown in Figure 22.



Figure 22. “Calculating the Gas Concentrations in Air” Progress Screen Once the zero references have been calculated, the TRANSPORT X is ready for the oil sample to be injected into the unit’s sample bottle.

4.3.1.3 Injecting Oil Samples Into the TRANSPORT X Having obtained a representative oil sample (see Section 4), it is important that the sample be handled correctly in order to ensure reliable results. Problems with sampling, storing or injecting the oil sample can all affect eventual results.

Note: If a sample is not tested immediately after being taken, it is recommended to store it in a dark, cool place.

Follow the following procedural steps to inject the sampled oil into the TRANSPORT X sample bottle. If the oil was hot when the sample was taken, shake the oil sample with a slight positive pressure on the syringe plunger before submitting it to the TRANSPORT X for analysis. The reason for this advice is that if the oil was hot when the sample was taken, it is possible for gas from the sample to come out of solution and form a bubble as the oil cools. By shaking the sample with a slight positive pressure on the syringe, the gas should be dissolved back into the oil and the sample should then be ready for analysis. Once the sample is confirmed to be correct, follow the on-screen instructions in the Gas Analysis Instructions screen (see Figure 23) to inject the oil sample. These instructions are described in more detail in the rest of this Section 4.3.1.3.

Figure 23. Gas Analysis Instructions Screen



Only 90 seconds are available to complete the injection process. The Gas Analysis Instructions screen displays a progress bar representing the run-down of these 90 seconds and the Time remaining for sample injection is displayed on the screen. The TRANSPORT X also emits a beep sound at 5-second intervals during the injection period. If the sample injection is not completed in the 90-second injection period that is available, the Sample Injection Timeout screen is displayed (see Figure 24). The user is then required to press the OK button and return to the start of the injection process.

Figure 24. Sample Injection Timeout Screen Prior to sample injection, the male quick-connect fitting should be attached to the syringe’s three-way stopcock (see Figure 25).

Figure 25. Male Section of the Quick-Release Valve Connected to the Syringe Connect the syringe to the sample bottle. The outer sleeve of the female fitting on the lid assembly should be held between the thumb and the forefinger and pressed downwards as far as it will go (see Figure 26). Insert the male quick-connect fitting that is attached to the syringe firmly into the female connector. A slight click is heard when the connection is fully made. Release the outer sleeve of the female connector to secure the connection.



Figure 26. Outer Sleeve of the Female Connector Turn the three-way valve 90 degrees to open the arm from the syringe to the bottle, thus closing the side arm of the valve (see Figure 27).

Figure 27. Stopcock (Three-Way Valve) With Side Arm Closed

Note: If the side arm of the valve is not closed, the oil will escape.

Slowly depress the plunger of the syringe fully. When the syringe is fully depressed, maintain gentle downward pressure on the plunger, wait 3-4 seconds and disconnect the syringe at the quick-release valve. To do this, press down the sleeve of the female section and lift the syringe, three-way valve and male quick-connect assembly away from the female section. Take care not to separate the male quick-release section from the valve/syringe until the syringe is disconnected from the bottle at the quick-release valve as that would provide an open channel for the gases to escape to atmosphere. Press the Next button on the Gas Analysis Instructions screen (Figure 23) to proceed with the sample analysis.

4.3.1.4 Sample Analysis Once the sample has been injected into the bottle, the temperature of the oil is measured. This is to avoid condensation in the internal pipe-work of the system. Therefore it is recommended that “hot”



oil not be tested, and that it has time to cool. The important criterion is that the analysis cell is warmer than the oil so it may be necessary to allow the unit to warm up if it has been stored in a cold location prior to use. The temperature measurement takes 90 seconds. If the oil temperature is higher than the internal cell temperature, then the sample analysis will not continue. The screen will display this temperature difference and its countdown (see Figure 28). Do not remove the bottle from the bottle holder cavity during this period. When the temperature difference figure reaches 0.0 °C, the unit will automatically start the analysis, possibly with a delay while the unit resets. Ensure the bottle is in place in the holder when the unit commences the analysis.

Note: If the bottle is not in place at this time, the magnetic stirrer will not operate and therefore the results will not be correct.

Figure 28. Temperature Countdown Screen After the oil temperature measurement has been taken, the unit begins the process of measuring the dissolved gases in the oil sample. Progress in making the measurements is shown by the display, in succession, of the Direct Moisture Measurement Progress screen (see Figure 29) and the Measuring Dissolved Gas Concentrations Progress screen (see Figure 30). The measurements take approximately 22 minutes to complete.

Note: Do not touch or remove the bottle from the holder during the measurement process.

Figure 29. Direct Moisture Measurement Progress Screen



Figure 30. Measuring Dissolved Gas Concentrations Progress Screen When the measurement procedure is complete, the results of the measurement are shown on the Results screen (see Figure 31). It shows the concentration levels of the various dissolved gases and the Total Dissolved Combustible Gas (TDCG) level that have been measured in the sample oil. The % Relative Saturation (% RS) of the sample is also displayed if the Sample Oil Extraction Temperature was entered into the TRANSPORT X’s diagnostic software (Figure 16).

Figure 31. Results Screen (Oil Sampling Point) Pressing the Next button displays the Results Options screen shown in Figure 32.



Figure 32. Results Options Screen The Results Options screen makes available to the user a number of options for the next step:

Print Results: to activate the TRANSPORT X’s built-in thermal printer and produce a hardcopy printout of the dissolved gas measurement results. When this button is pressed, the Printing screen (see Figure 33) appears whilst the printing is in progress. An example of the type of printout that is available is shown in Figure 34.

Figure 33. Printing Screen

Advanced…: to continue analysis of the measurement results using the TRANSPORT X’s embedded DGA diagnostic tools (see Section 4.3.2).

Finish: to store the measurement results in the TRANSPORT X’s database.

Cancel: to abort the measurement results and delete it from the TRANSPORT X’s memory.

4.3.2 Analysis Tools

Note: The analysis tools incorporated into the TRANSPORT X do not represent the opinion of GE Energy; rather they are based upon widely recognized standards and algorithms, with the various caution and warning alarm thresholds set by the user.

By selecting Advanced… in the Results Options screen (Figure 32), the operator can use the incorporated software tools to aid in the analysis of DGA results. This option is only available for Transformer oil samples. If the user has entered Tap Changer, Circuit Breaker or Other in the Equipment Type screen (Figure 7), then the analysis tools do not apply.



Figure 34. Results Printed by the TRANSPORT X’s Built-in Thermal Printer

4.3.2.1 DGA Analysis Using Caution and Warning Thresholds The first diagnostic tool made available to the user after pressing the Advanced… button found in the Results Options screen (Figure 32) is that which compares measured dissolved gas concentration levels with the preset Caution and Warning levels for each gas that were previously entered into the TRANSPORT X diagnostic software.

Note: Default gas concentration threshold levels have been pre-programmed into the TRANSPORT X diagnostic software, but the thresholds are settable by the user, as described in this Section 4.3.2.1.

If the measured concentration value for any gas is above one of the threshold levels for that gas, an appropriate warning is advised to the user. For example, if the DGA measurement for a particular gas is above either the Caution or Warning threshold levels, that situation is highlighted in yellow (if above the Caution level) or red (if above the Warning level) on the Analysis screen (see Figure 35). An overall Transformer Condition of Normal, Caution or Warning can be provided based upon these alarm levels.



Figure 35. Analysis Screen Showing Caution and Warning Levels The operator can examine the current gas concentration threshold settings, or limits, by pressing the View Limits… button shown on the Analysis screen above. The limits are then displayed in the Gas Concentration Limits screen (see Figure 36).

Figure 36. Gas Concentration Limits Screen To change the Caution and/or Warning threshold levels, return to the Main Menu screen (Figure 5) and press the Settings button followed by the Gas Limits button. The Gas Concentration Limits Reset screen is displayed (see Figure 37). By highlighting in turn each gas displayed on this screen using the Up and Down arrows, their Caution Limit and Warning Limit levels can be reset as desired using the appropriate Up and Down arrows.



Figure 37. Gas Concentration Limits Reset Screen The Default button on the Gas Concentration Limits Reset screen resets the gas concentration thresholds to the default Caution and Warning levels. If this button is pressed, the Default Reset Warning window is displayed (see Figure 38). Click the Yes button to continue resetting the thresholds to the default levels.

Figure 38. Default Reset Warning Window When the desired thresholds have been set in the Gas Concentration Limits Reset screen (Figure 37), press the OK button to return to the Settings screen.

4.3.2.2 DGA Analysis Using Diagnostic Algorithms The operator can select the Diagnosis… option shown in the Analysis screen (Figure 35) to give access to four analysis diagnostic tools: Key Gas (see Figure 39), Rogers’ Ratios, Duval’s Triangle and Japan ETRA (see Figure 40). Access to these analysis options is obtained by pressing the tab of the desired option found at the top of the screen.



Figure 39. Analysis Screen – Key Gas Tab

Figure 40. Analysis Screen – Japan ETRA Tab These analysis tools are based on empirical data derived from the study of transformer degradation and failures. They are not designed for the detection of transformer faults – rather they are intended to provide warning of potential failures or aid in the diagnosis of transformer faults. If the gas levels are very low and the transformer does not appear to have a fault, then these algorithms can give misleading results and should not be applied. The user-settable thresholds discussed in Section 4.3.2.1 are very useful for this purpose. These issues are explained fully in the standards and references that are cited on the tabs that relate to the individual analysis tools found in the Analysis screen (Figures 39 and 40). To use a particular diagnostic method, press the button for the appropriate tab located along the top of the Analysis screen (Figures 39 and 40). This action will cause re-configuration of the Analysis screen to reflect the chosen diagnostic option. Then press the button bearing the name of the selected diagnostic method (found in the central Diagnosis Information panel of each Analysis screen) to enter the selected diagnostic algorithm.

Note: for the Japan ETRA case shown in Figure 40, there are two Diagnostic buttons in the central Diagnosis Information panel, entitled Gas Pattern and Diagnostic Diagram.

1) Key Gas Method – IEEE C57.104-1991 This technique allows visual comparison of the measurement result with 4 “typical” fault results. The user should determine which typical result, if any, matches most closely the TRANSPORT X result. The user can scroll through the 4 “typical” failure options using the arrow keys. These failure options appear on the touch screen as pink columns alongside the TRANSPORT X result, which is shown by



the blue columns (see Figure 41). The user should choose the failure option that most resembles their own result from the diagnosis by pressing the Select button on the appropriate option screen. If there is no applicable comparison, the user should not make a diagnosis selection and press the Cancel button, which equates to selecting the None diagnosis. Pressing either the Select or Cancel button returns the display to the Analysis screen (Figures 39 and 40).

Figure 41. Key Gas Method (Showing Overheated Oil as the “Typical” Failure Comparison) 2) Rogers’ Ratios – IEEE C57.104-1991 This method uses established ratios between various dissolved gases to determine the type of fault (see Figure 42). However, if the gas concentration levels are low, the Roger’s Ratios screen will show a warning that gas levels may be too low for this algorithm to produce a reliable result. The fault code and diagnosis may still be displayed, but caution should be used when applying this result. Press the OK button to return to the Analysis screen (Figures 39 and 40).

Figure 42. Rogers’ Ratios Screen 3) Duval’s Triangle – TechCon 2004 – Michel Duval Duval’s method uses a triangle to plot the intersecting point of certain gas concentration values (see Figure 43). Where this point is located within this triangle indicates the type of fault the transformer may have. The diagnosis is indicated at the bottom right of the Duval Triangle screen. Press the OK button to return to the Analysis screen (Figures 39 and 40).



Figure 43. Duval’s Triangle Screen (Showing Low Energy Discharges) 4) Japan ETRA – Volume 54, No. 5 The Japanese Electric Technology Research Association (ETRA) has reviewed many DGA diagnoses in Japan and elsewhere and has reached certain conclusions regarding the detection of faults in transformers. From these studies a series of patterns have been produced that depict the relative concentration levels of certain dissolved gases (H2, CH4, C2H6, C2H2 and C2H4) present in the oil of failing transformers at the time internal faults appear and these patterns have been associated with specific types of failure. They have also developed two diagnostic charts or diagrams that are based on the ratios of concentrations of certain dissolved gases that have been correlated with particular types of transformer failure. These two forms of failure diagnosis have been incorporated into the TRANSPORT X’s failure analysis suite. a) Gas Pattern Analysis Method Press the Gas Pattern button located in the central Diagnosis Information panel under the Japan ETRA tab of the Analysis screen (Figure 40). A series of dissolved gas patterns (see Figure 44) are then made available using the forward or backward arrows, each pattern being derived from the Japan ETRA analysis of transformer failures. Also included for comparison purposes is the pattern, produced in an identical manner to the ETRA failure patterns, that is based on the TRANSPORT X measurements.

Note: All these patterns have been produced by a normalization process using the concentration level of the dissolved gas with the highest concentration discovered in the oil of a failing transformer.

Figure 44. Gas Pattern Based on TRANSPORT X Measurements



In Figure 44, the most recent set of dissolved gas concentration measurements made by the TRANSPORT X are displayed. It can be seen that the measured concentration of C2H4 has been used to normalize the concentration levels of the other measured dissolved gas constituents. Thus the measured concentration of C2H6 is approximately 37 % of the concentration of C2H4. In Figure 45 we find the ETRA pattern for a type C2H4-A failure displayed in the right-hand chart with the measured gas pattern previously depicted in Figure 44 shown in the left-hand chart. The TRANSPORT X makes available a number of such ETRA gas patterns, each pattern representing a different type of failure. The user is required to decide which of the available patterns is closest to their measured pattern and then by using the Select button choose that pattern (or none) as the failure pattern.

Figure 45. C2H4-A Type Failure Pattern Compared With Gas Pattern Based on TRANSPORT X Measurements

b) Diagnostic Chart Method Press the Diagnostic Diagram button located in the central Diagnosis Information panel under the Japan ETRA tab of the Analysis screen (Figure 40). On the first diagram (Diagram A) shown in Figure 46, the white spot is the result derived from the most recent set of dissolved gas concentration measurements made by the TRANSPORT X for the particular gas ratios used in this chart. It can be seen that in this instance the diagram suggests that the transformer failure is because of Discharges.

Figure 46. Japan ETRA Diagnostic Diagram A



Press the button to display the Diagnostic Diagram B (Figure 47). As previously with Diagnostic Diagram A, plotted on this diagram (as the white spot) is the result derived from the most recent set of dissolved gas concentration measurements made by the TRANSPORT X using the gas ratios of Diagnostic Diagram B. It can be seen that in this instance the diagram suggests that the transformer failure is because of Partial Discharge (Low Energy). Press the OK button to return to the Analysis screen (Figures 39 and 40).

Figure 47. Japan ETRA Diagnostic Diagram B

4.3.2.3 Concluding the Analysis Process Press the OK button on the Analysis screen (Figures 39 and 40), and then press the OK button on the DGA Analysis screen (Figure 35). These actions cause the Analysis Conclusion screen (see Figure 48) to be displayed.

Figure 48. Analysis Conclusion Screen This screen presents the user with the following options:

Print Results: to print the results (both Measurement Results and Diagnostic Analysis Results). The Print process is as described previously in relation to the Results Options screen (Figure 32).

Advanced…: to re-enter the Analysis process. The user is returned to the beginning of Section 4.3.2, i.e. to the analysis of the measurement result using the TRANSPORT X’s embedded DGA diagnostic tools.



Finish: to finish the measurement and analysis process. The measurement and analysis results are saved in the TRANSPORT X database and the database is then closed (see Figure 49).

Figure 49. Saving and Closing the Database Once the database is closed, the Clean Up screen (see Figure 50) is displayed. This screen contains instructions to the user to disconnect the sample bottle and shut down the TRANSPORT X following the DGA measurement and diagnosis.

Figure 50. Clean Up Screen Press the Next button to return to the Main Menu screen (Figure 5) for shutdown of the unit.

4.3.3 Internal Error Checking The TRANSPORT X includes a function for monitoring the internal operation of the system and checking the validity of oil samples. If an anomaly is detected, then this will be reported to the user at the end of the sample measurement process. In addition, any result invoking an error code is highlighted in yellow in the database Records screen (see Figure 51) – see also Section 4.3.4 for further information about the database Records screen.



Figure 51. Records Screen (Database List Showing 2 Results With Errors) The user can navigate to a stored result in the Records screen by using the Up and Down arrows. The result highlighted in grey/blue is the current or active result. When the user navigates to a result which is subject to an error, the Caution button is displayed advising the user that the highlighted result contains some sort of error. This feature is illustrated in Figure 51, where the database list contains two results containing errors, one of which is the active result causing the Caution button to be displayed. Pressing the Caution button causes the ErrorCheck Results screen (see Figure 52) to be displayed.

Figure 52. ErrorCheck Results Screen Error codes for each fault detected by the TRANSPORT X unit are displayed in the Code column of the ErrorCheck Results screen. Error codes are divided into two main types – hardware or instrument, and gas or environmental errors. The ErrorCheck Results screen gives an example of a hardware error. The hardware type of error relates to an issue with the TRANSPORT X unit, whereas the gas type describes issues with the sample being measured or the local environment:

Hardware error classified as a Warning (highlighted in red): the user should contact the GE Energy Customer Support immediately as a malfunction with the TRANSPORT X unit has been detected.

Hardware error classified as a Caution (highlighted in yellow): the user should take certain action, such as change the in-line filters. If this code persists, the user should contact the GE Energy Customer Support.



Gas error classified as a Warning (highlighted in orange): the TRANSPORT X had detected a serious problem with the sample. This would mainly be caused by interference of the sample from a solvent and the results from such a sample could not be relied upon.

Gas error classified as a Caution (highlighted in white): an issue has arisen with the sample, but the results are still valid, albeit they may have a larger than normal margin for error. Such a situation may be caused by high target gas levels being detected in the ambient air. In such a situation, the user could potentially take the TRANSPORT X unit to another location for further sample testing or increase the purge time for future tests.

If the instrument detects any error codes, the user is given the option of resolving the problem using the Resolve button that is found at the bottom of the ErrorCheck Results screen (Figure 52). By pressing the Resolve button, the user is presented with the ErrorCheck Response screen (see Figure 53), where the two best options for preventing a reoccurrence of the error are displayed.

Figure 53. ErrorCheck Response Screen The user should follow the instructions in the First response and, if this fails to fix the issue, proceed to the Second response. If the Resolve function is not used, the user may consult the Troubleshooting Guide (Section 9) and follow the suggestions for action to resolve the error. If the error cannot be resolved, contact GE Energy. If the user chooses to continue a measurement having failed to resolve the issues highlighted, results may be affected. A warning to this effect will be given in the Potential Error Warning window (see Figure 54).

Figure 54. Potential Error Warning Window



4.3.4 Viewing Previous Results The TRANSPORT X offers users the option of examining results stored in its database. To do this, press the View Previous Results button on the Main Menu screen (Figure 5). The options for searching the database are then displayed on the Display Results screen (see Figure 55).

Figure 55. Display Results Screen The Show All Results button is highlighted (in red) as the default option when this screen is first displayed. Pressing the Next button when the Show All Results button is highlighted causes the database Records screen (Figure 51) to be displayed. The Records screen displays all the database records without any application of a search category. The organization of the database is based upon information categories entered by the user when doing the DGA tests and this information is searchable using the Display Results screen. To display a particular result (as compared to displaying all the database records in the Records screen), the user should first select the desired search category button on the Display Results screen and then press the Next button – all the data entered in the database under the selected category is then displayed. As an example of the database search process, to conduct a search based on the location category, first press the Location button on the Display Results screen. All the location records entered in the database are then listed in the Equipment Location screen (Figure 8). Using the scroll buttons on the Equipment Location screen, highlight the location that is of interest. Then by pressing the Next button at the bottom of the Equipment Location screen, all the records for this one location will be displayed in a list on the database Records screen (Figure 51). To display the results for a particular record, highlight the record of interest using the Up and Down arrows, then press the View Result button. The results can then be printed and/or analyzed as previously described in relation to the Results Options screen (Figure 32). All searches for a particular record stored in the database are conducted in a manner similar to that described above for a location-based search, although there is a minor variation for the Date of Sample search. In the case of a Date of Sample search, the user is required to commence the process by setting start and end dates for the query. Therefore, Start Date and End Date screens of the form shown in Figure 56 are displayed successively at the beginning of the process for setting the date range of the search of the database records. The user should first enter the start date of the search on the Start Date screen. Then by pressing the Next button on the Start Date screen, the End Date screen is displayed; the end date for the search should then be entered on the End Date screen. Dates are entered on both the Start Date and End Date screens in the same manner. The forward and back calendar arrows on the Date screens are used first to select the required year/month combinations and then the days are indicated by highlighting the required days on the displayed monthly calendars.



Figure 56. End Date Screen

4.3.5 Settings Pressing the Settings button on the Main Menu screen (Figure 5) causes the Settings screen shown in Figure 57 to be displayed.

Figure 57. Settings Screen The various buttons on this screen enable the user to perform the following functions:

Note: The database is pre-populated with a number of Time Zones relative to GMT. The user should select the zone closest to their time zone.

Figure 59. Date/Time Picker Screen After making the required Date, Time and Time Zone settings, a warning message is displayed asking whether the user wishes to proceed with implementation of the changes. Press the Yes button on this warning screen if the changes are in order. A second screen is then displayed indicating that the Date and Time have been updated; press the OK button on the second screen to return to the display of the Settings screen.

4.3.5.2 Performing System Housekeeping, Checking and Maintenance Functions By pressing the System… button on the Settings screen (Figure 57), the System screen (see Figure 60) is displayed. On this screen are found details of the last times when a System Check was performed.



Figure 60. System Screen From this screen, four option functions can be accessed:

Start System Check: see Section 8.

Advanced…: this option is password-protected and is only for the GE Service staff.

Start System Flush: see also Section 4.2. Pressing the Start System Flush button on the System screen initiates a flushing process whereby ambient air is circulated through the TRANSPORT X for 20 minutes in order to help clear any potential contamination from packing material or prior samples from the system. Pressing the Start System Flush button causes a caution window to be displayed (see Figure 61).

Figure 61. System Flushing Caution Window

Click the Yes button to continue. The System Flush Instructions screen is then displayed (see Figure 62).



Figure 62. System Flush Instructions Screen

Follow the on-screen instructions by connecting a clean, dry sample bottle to the unit as detailed. Press the Next button to initiate the system flushing. The Flushing Progress screen (see Figure 63) is then displayed. The process takes approximately 20 minutes to complete. The Cancel button on this screen can be used for early termination of the flushing process.

Figure 63. Flushing Progress Screen

When the flushing is completed successfully, the System Flush Completed screen is displayed (see Figure 64). Press the Next button to return to the Main Menu screen (Figure 5).



Figure 64. System Flush Completed Screen

Start Pressure Test: the Pressure Test follows an identical process to the System Flush process (above). The unit is checked for its ability to maintain pressure in the working gas system. If pressure can be maintained, the Pressure Test Passed screen is displayed (see Figure 65).

Figure 65. Pressure Test Passed Screen

If pressure cannot be maintained (i.e. a leak is detected) in the working gas system, the Pressure Test Failed screen is displayed (see Figure 66). In this case, follow the on-screen instructions and re-run the Pressure Test.



Figure 66. Pressure Test Failed Screen

5. TAKING AN OIL SAMPLE

The sampling procedure provided below has been adapted from the international standard IEC 567 for the sampling of oil from oil-filled electrical equipment for the analysis of dissolved gas. Correct sampling of the insulating oil is essential to ensure that a representative sample is obtained which will give an accurate snapshot of the overall condition of the oil within the equipment. The method recommended here for sampling ensures that a secure sample is obtained and is ready for injection into the TRANSPORT X without risk of contamination, post or pre sampling. The method is described with the aid of reference to diagrams (Figures 67 to 70). The technique assumes that there is an available fitting on the equipment to be sampled that will allow connection of a two-way Luer lock valve directly to the equipment, either in-line in a sampling pipe, or as a fitting that can be connected directly to the sampling point. Many different configurations are possible but the requirement is the same for all. The sample container consists of a 50-mL ground glass syringe to which is connected a two-way plastic stopcock. Although this stopcock is removable from the syringe, for the purpose of this sampling description, it should be considered as part of the syringe/sample container assembly. Proceed as follows: 1. Connect the syringe via a Luer lock 3-way valve to the equipment sampling line. 2. Turn the valve in the equipment sampling line and the valve on the syringe to allow equipment oil

to flow out to waste from the syringe valve (see Figure 67). Allow at least 1 liter of oil to flow to a waste container.

Figure 67. Allow Equipment Oil to Flow out to Waste 3. Turn the syringe valve to the position where oil can be drawn into the syringe (see Figure 68). 4. Gently draw oil fully into the syringe. At this stage bubbles of air from the dead volume in the

neck of the syringe are drawn into the syringe and some of the gas present is dissolved into the oil. Also some of the gas in the oil escapes into the air bubbles. This oil and gas must be rejected as unrepresentative of the oil in the transformer.



Figure 68. Draw Oil Into the Syringe 5. Turn the Luer lock valve fitted to the equipment sampling line to allow oil to flow out from the

syringe to a waste container. At the same time, holding the syringe upright, expel all of the bubbles and almost all of the oil from the syringe (see Figure 69).

Figure 69. Expel Oil and Air From the Syringe



6. Close the syringe valve when most of the oil has been expelled, leaving approximately 2 mL of oil remaining in the syringe.

7. Turn the syringe valve to permit the gentle drawing of 50 mL of oil into the syringe (see Figure 70).

Note: The head pressure from the transformer main tank may actually push the oil into the syringe so care must be taken not to allow the plunder to come out the end of the syringe body at this point.

Figure 70. Draw Oil Into the Syringe 8. Flush this oil out of the syringe into the waste container. 9. Repeat the steps 7 and 8 at least 2 times. 10. Draw exactly 50 mL of oil into the syringe. 11. Turn the equipment valve to prevent any further oil escaping from the transformer. 12. Turn the syringe valve to the fully closed position. 13. Disconnect the syringe from the equipment sampling line. A representative sample of oil from the equipment is now ready for injection into the TRANSPORT X.

6. CLEANING THE APPARATUS

After performing a test, it is important to use the correct clean-out procedure to avoid any contamination from one sample to the next. A small amount of residual oil left in the sample container or injection pipe-work may have an impact on the results and diagnosis obtained from the TRANSPORT X for the next sample.

Note: DO NOT use any solvents to clean any part of the TRANSPORT X or its accessories as this can affect results.

6.1 CLEANING THE SYRINGE, VALVES AND LID ASSEMBLY

The sample bottle, the syringe with its 3-way valve, the male quick-connect valve that is connected to the syringe, and the oil injection tube in the lid assembly should be cleaned out after every sample analysis. The sample bottle, the syringe inner surfaces (barrel and plunger) and the lid assembly are cleaned using clean absorbent cloth or tissue. The syringe with its 3-way valve, the male quick-connect valve and the oil injection tube are cleaned by air pumped from the syringe. By following these best practices, the TRANSPORT X can easily clear the effects of heavily gassed samples for the next test.

6.2 CLEANING THE SYRINGE

It is imperative that the syringe is kept clean in order to prevent cross-contamination of results. The syringe cleaning steps are as follows. 1. Wipe all surfaces with an absorbent cloth or tissue. 2. Ensure the male quick-release valve (Figure 25) is connected to the syringe. 3. Turn the 3-way valve on the syringe to permit air to be drawn into the syringe through the side

arm of the valve. 4. Draw in air to the syringe through the side arm of the valve. 5. Hold the syringe with the quick-release valve pointing vertically down. 6. Turn the 3-way valve to open the in-line arm and close the side arm. 7. Push air through the syringe and valves, flushing out any oil residue. 8. Repeat 4 or 5 times the steps 3 to 7.



This process will flush oil out of the syringe, the 3-way valve fitted to the syringe and the male quick-connect valve.

Note: When performing the above cleaning process, use a cloth or waste container to expel excess oil into.

Note: It is recommended that the user thoroughly cleans the syringe after each sample and before storage / reuse. To do so, remove the plunger from the syringe barrel. The plunger and barrel are both then cleaned with a cloth or tissue.

Note: Ensure no oil residue remains in the quick release valve or syringe 3-way valve. Use the technique of vigorously flushing air through these valves using the syringe as a pump, as described above.

6.3 CLEANING THE BOTTLE AND LID ASSEMBLY

After the TRANSPORT X has completed its analysis, the oil sample should be disposed of properly and the bottle and lid assembly cleaned as described below.

Note: The same oil sample cannot be re-tested as most of the gas will have escaped during analysis.

The sample bottle and lid cleaning steps are as follows. 1. Unscrew the lid assembly from the sample bottle, holding the lid assembly upright to avoid any

oil ingress into the tubes. 2. Clean the lid assembly underside and pipes with a clean cloth. 3. Connect the syringe to the lid assembly using the male quick-connect valve connected to the

syringe (Figure 25) and the female quick-connect valve located in the lid assembly (Figure 26). 4. Expel any oil residue from the oil injection pipe by flushing through with air pumped from the

syringe 4 or 5 times. 5. Give the bottle a thorough clean with a cloth or tissue. If no other test is undertaken at this location, disconnect the pipe work from the top panel of the TRANSPORT X, screw the lid assembly back onto the sample bottle, and place the sample bottle/lid assembly (including the connecting tubes with filters) back in the accessories case (see Figure 3).

7. SAMPLING AND ANALYZING GASES FROM GAS-COLLECTING (BUCHHOLZ) RELAYS

Gas samples from relays should be taken from the equipment with minimum delays after gas accumulation has been signaled. Changes in composition caused by the selective re-absorption of gas into oil may occur soon after an event. Gas samples must be analyzed without undue delay to minimize gas loss, specifically hydrogen. The apparatus in the sampling kit includes:

A 5-mL gastight syringe with Luer lock termination and integrated valve

A length of 3.17 mm (1/8 inch) ID gas impermeable plastic tube

A 3-way plastic stopcock with Luer terminations male-male-female. The procedure is as follows.

7.1 GAS SAMPLING

1. Connect the Buchholz sampling point to the stopcock of the syringe using the plastic tube supplied (see Figure 71).

2. Allow any oil in the sampling tube to run to waste.



Figure 71. Allow Oil in the Sampling Tube to Flow out to Waste 3. When gas starts to flow, adjust the 3-way stopcock to allow the gas to fill the syringe by the

hydrostatic pressure in the relay (see Figure 72), taking care that the gas pressure does not eject the plunger completely.

Figure 72. Allow the Gas to Fill the Syringe 4. When the syringe is filled to the 5-mL mark, turn the 3-way stopcock again (see Figure 73) to seal

the gas in the syringe ready for injection into the TRANSPORT X. 5. Disconnect the syringe/stopcock from the tubing. 6. Analyze the gas sample immediately or as soon as possible after collecting the sample.



Figure 73. Seal the Gas in the Syringe

7.2 GAS SAMPLE INJECTION AND ANALYSIS

1. Select Start New Measurement from the Main Menu screen (Figure 5). 2. Follow the on-screen instructions and as previously outlined in Section 4.3.1.1, enter all the data

for the sample. 3. However, for a gas sample there are some differences to the procedure previously outlined for

doing measurements and analysis on a gas sample. For example, when prompted to enter the Equipment Sampling Point for the sample (Figure 13), enter Buchholz Relay.

4. In the Sample Source screen (see Figure 74), select Gas Sample.

Figure 74. Sample Source Screen (With Gas Sample Selected) 5. Upon selecting Gas Sample, the warning message regarding the lower detection limit for gas

samples is displayed (see Figure 75). 6. Press the OK button after noting the displayed warning. This action returns the user to the

previous Sample Source screen. 7. Press the Next button on the Sample Source screen and then, as for an oil sample, the Details

screen (Figure 15) is displayed - but with the Sample Source being displayed as Gas Sample. 8. Check and confirm all the information that has been entered into the database before

continuing.



Figure 75. Lower Detection Limit Warning Window 9. The Optional Details screen (Figure 16) is then displayed and this is responded to as previously

outlined for an oil sample. 10. Install the sample bottle and lid assembly as for an oil sample (although there is no need for the

magnetic stirrer piece in the Sample Bottle). 11. When prompted on-screen to inject the gas sample, connect the syringe containing the sample

gas to the sample bottle via the quick-connect fitting (similar to injecting an oil sample). 12. Open the valve on the syringe. 13. Depress the plunger fully. 14. Leaving the syringe and valve in the same position, draw the plunger back to the 5-mL mark (be

careful not to remove it completely). 15. Depress the plunger fully again. 16. Pulling down on the outer sleeve of the quick-connect fitting, disconnect the syringe and the

quick-connect from the Sample Bottle, similar to disconnecting the syringe when testing an oil sample.

17. Press Next to continue. 18. Wait for the results to be displayed on the Results screen (see Figure 76). This screen is similar to

that described for an oil sample (Figure 31) except that the Sampling Point is shown as a Gas Sampling Point.

19. As for an oil sample, the results can be printed using the TRANSPORT X thermal printer. 20. The results are also stored in memory when pressing the Finish button.

8. SYSTEM CHECK

Due to the inherent stability of the TRANSPORT X, routine calibration of the detector is not necessary. Recalibration is only necessary in the event of a serious fault occurring with the PAS (photo-acoustic spectroscopy) system or due to misuse of the instrument. Under these circumstances, this recalibration must be performed by the manufacturer. However, it is recommended that the user should periodically assess the operation of the TRANSPORT X using the System Check procedure. This procedure can be performed as often as wished but should be undertaken nominally every three months. The System Check allows the user to confirm that the TRANSPORT X PAS calibration is functioning correctly. Section 4.3.5.2 has described the System Housekeeping, Checking and Maintenance functions of the TRANSPORT X, although details of the System Check procedure were not given at that stage. Instead those details are provided here.

8.1 SYSTEM GAS CHECK PROCEDURE

The check procedure involves the use of the System Check Kit apparatus (see Figures 79 and 80 below). This kit consists of a cylinder of gas containing all the DGA target gases at known concentrations, together with a length of Nafion® tubing, used to connect the gas cylinder to the inlet connector on the top panel of the TRANSPORT X. By pressing the System… button on the Settings screen (Figure 57), the System screen (Figure 60) is displayed. On this screen are found details of the last times when a System Check was performed. Press the Start System Check button to commence the System Check process; the user is then presented with the System Check Caution window (see Figure 77).

Figure 77. System Check Caution Window Press the Yes button to continue the System Check process. This action causes the System Check Flush With Air screen to be displayed (see Figure 78). Follow the on-screen instructions and set up the System Check Kit apparatus (see Figures 79 and 80 below). When setting up the System Check Kit:

Do not put the oil sample bottle into its holder.

Do not connect the bottle lid assembly to the top panel of the TRANSPORT X.



Figure 78. “System Check Flush With Air” Screen

Connect the Nafion® tubing to the cylinder fine-adjustment control valve by pushing the flexible, black viton tubing over the barb connector on the outlet from the cylinder Mini Flow Control Knob (see Figure 79).

Figure 79. Details of Viton Tubing Connection to Mini Flow Control Knob and Flow Indicator Setting

Connect the other end of the Nafion® tubing, which is fitted with a male quick-release connector, to the top-panel female quick connector on the TRANSPORT X (see Figure 80).

Figure 80. Connection of the Check Gas Cylinder to the TRANSPORT X via a Nafion® Tube Once these preparations are completed, press the Next button at the bottom of the System Check Flush With Air screen (see Figure 78). The Flushing With Air Progress screen is then displayed (see Figure 81). The air flushing takes approximately 14.5 minutes.

Figure 81. Flushing With Air Progress Screen When the air flushing process has been completed, the System Check Flush With Gas Mixture Progress screen is automatically displayed (see Figure 82). This screen instructs the operator to open the gas mixture regulator on the gas cylinder (Figure 80) and to set the rate of gas flow to the TRANSPORT X at 500 mL/minute (i.e. approximately quarter to half of the maximum flow rate). The flow rate is controlled using the Mini Flow Control Knob on the cylinder gas regulator. This knob should be turned slowly in an anticlockwise direction until the desired flow rate is achieved. The correct flow rate is indicated by the small metal ball in the flow channel being lifted to the point where it is between the 1st and 2nd graduation in the clear plastic flow cell attached to the flow regulator.

Figure 82. System Check Flush With Gas Mixture Progress Screen The operator has only a limited time period (1.5 minutes) for setting up the required gas flow to the TRANSPORT X. During this period, the TRANSPORT X can be heard emitting a beeping sound. Press the Next button at the bottom of the System Check Flush With Gas Mixture Progress screen when the correct gas flow rate is achieved. The Flushing With Gas Mixture Progress screen is then displayed (see Figure 83).

Figure 83. Flushing With Gas Mixture Progress Screen After approximately 2 minutes, when flushing of the TRANSPORT X unit with the test gas is completed, the unit begins the process of making gas concentration measurements on the test gas. The display screen automatically switches to the Measuring Gas Mixture Progress screen (see Figure 84). At this point, the user is instructed to close the gas regulator valve on the gas cylinder and to disconnect the Nafion® gas supply tube from the injection port on the top panel of the TRANSPORT X.



Figure 84. Measuring Gas Mixture Progress Screen The process of making the gas concentration measurements on the test gas takes approximately 3.5 minutes. When all the measurements have been made, the display screen changes to the System Check screen (see Figure 85). This is an added reminder to help avoid gas wastage.

Figure 85. System Check Screen Press the Next button at the foot of the System Check screen to reveal whether the TRANSPORT X has passed or failed the System Check. If the TRANSPORT X has successfully passed the System Check, the System Check Passed screen is displayed (see Figure 86). The measured gas concentration results will therefore be within ± 15 % of the true gas concentrations of the test gas.



Figure 86. System Check Passed Screen If the TRANSPORT X has failed the System Check, the System Check Failed screen is displayed (see Figure 87).

Figure 87. System Check Failed Screen In the event of a “Fail” result, the user should re-do the System Check, by pressing the Next button found at the bottom of the System Check Failed screen. Before re-doing the test, ensure there is no obstruction in the Nafion® tube assembly. This can be checked as follows:

Connect the Viton end of the Nafion® tube to the barb connector of the Mini Flow Control Knob on the cylinder.

Block the side arm of the Tee junction in the Nafion® tube.

Using the Mini Flow Control Knob, set the flow to 500 mL/min.

Place an obstruction momentarily over the open end of the Nafion® tube and note the effect this has on the flow rate.

If the flow rate drops but does not fall to zero, this indicates that there is still an open channel in the Nafion® tube.

The user should ensure the flow remains steady at 500 mL/min or more throughout the re-test by observing the position of the flow indicator ball throughout a 2nd test. If upon performing a re-test a second “Fail” result is produced, the user should re-do the System Check one more time. If this further test also fails, the user is directed to contact GE Energy by the Unit Failed System Check screen (see Figure 88). After studying the System Check results for the



unit, GE Energy may report a faulty unit and request its return or may make other suggestions for re-establishing functionality of the TRANSPORT X for the user.

Figure 88. Unit Failed System Check Screen

Notes: The cylinder of gas mixture is non-flammable and non-toxic; it should however only be used in a well-ventilated area by trained personnel. When empty, the cylinder can be disposed of by recycling or as normal domestic or industrial trash. The cylinder is pressurized to 300 psi at 20 °C when full and contains 12L of gas. Each test consumes at least 1 L of gas and so a full cylinder should be good for up to 12 System Checks. The gas mixture in the cylinder has a shelf life of 2 years from the date of manufacture – marked on the bottom on the cylinder.

8.2 HYDROGEN

A molecularly balanced gas compound, such as Hydrogen (H2) cannot be measured using PAS and is instead measured utilizing a tin dioxide (SnO2) semiconductor which has a low conductivity in clean air. So the nature of the System Gas Check and the tin dioxide sensor can result in H2 consumption and this may under certain circumstances incorrectly trigger an error with the H2 sensor. In order to eliminate such false failures, you should be running the latest release of the TRANSPORT X firmware (v 1.12.5.544 onwards). This effectively removes H2 from the System Gas Check procedure thereby restricting testing to the six photoacoustic gases. Note: The functionality to measure H2 during normal TRANSPORT X operation remains unchanged by this change to the System Gas Check procedure. If the TRANSPORT X unit fails the System Gas Check, follow these steps: 1. Check the firmware version 2. If it is older than the version above, update the TRANSPORT X firmware 3. Re-run the System Gas Check procedure 4. If it passes, then everything is OK 5. You should only contact GE if it subsequently fails the test after the new firmware upgrade

9. TROUBLESHOOTING

In Section 4.3.3, the user was advised to consult the Troubleshooting Guide (this Section) in those instances where the TRANSPORT X had detected an internal error and the Resolve function had not proven able to fix the problem. Table 2 presents the Troubleshooting Guide referred to in Section 4.3.3. To use the Troubleshooting Guide, the user must first note the Error Code that was displayed on the ErrorCheck Results screen (Figure 52) when the error was detected, then trace the references to that same Error Code through the Troubleshooting Guide until the suggested remedies (1st Response and 2nd Response) are discovered.

All the files on the TRANSPORT X are stored in the directory My Computer / Mobile Device / My Computer / FlashFx Disk. The Log File can be found in FlashFx Disk\\Results\\Logfile.dat and can be copied to a location on the user’s PC.

Note: There is also a file named LogFilex.dat in this location. This is not required.

Please email the Log File to GE Energy for inspection by a GE Energy engineer.

11. EXCHANGING A BOTTLE LID ASSEMBLY

Each TRANSPORT X has a bottle lid assembly assigned to it and bottle lid assemblies cannot normally be exchanged between instruments. If a user must use a new bottle lid assembly for their instrument, they will need to adjust the settings file on their TRANSPORT X to include the new calibration factors associated with the capacitance moisture sensor which is incorporated into the bottle lid assembly temperature probe.



Note: This issue does not affect any units in the field that do not have capacitance sensors. These can be recognized by three pins in the plug coming from the bottle lid assembly (capacitance sensor units have four pins) – for those lid assemblies can be interchanged without modification of any settings.

Each replacement bottle lid assembly will be supplied with a card or sheet detailing the calibration factors of the new sensor. Each lid will have a 2- or 3-digit code engraved on the sensor probe that must match the “Channel Number” on the calibration slip. For an example of the calibration details sheet, see Figure 89.

Note: The structure of this sheet may not be identical to that shown but the essential details will be included.

Figure 89. Example of Calibration Factor Sheet Provided With Replacement Bottle Lid Assembly The values which must be reset in the TRANSPORT X are the Slope (kw) and the Zero Offset (zw). To change these the operator must navigate to the appropriate section of the instruments software. From the Main Menu screen (Figure 5), select Settings and then Advanced. A menu title Bottle lid then shows the calibration factors for the current bottle lid (see Figure 90) and allows the operator to insert the new calibration factors. If it is intended to switch back to the original lid assembly in the future, record and retain these calibration factors with the bottle lid they are associated with.

Figure 90. Bottle Lid Current Calibration Factor Selecting the option Bottle lid takes the operator to the screen shown in Figure 91. From here a current set of calibration factors can be selected if an old lid assembly is been reused or details of a new lid assembly can be entered using the keyboard similar to Figure 10. A name may also be applied to a particular sensor for future reference.



Figure 90. Entering Calibration Details for a Replacement Bottle Lid Assembly After the calibration factors have been entered, the operator may proceed to use the new bottle lid assembly for routine measurements.



APPENDIX 1: OPERATING ENVIRONMENT FOR DGA EQUIPMENT

In line with the operation of any gas analysis equipment, it is a requirement of the TRANSPORT X operation that testing is performed in a clean, local, ambient environment free from excessive atmospheric pollutants and excesses of temperature or pressure. Details of pressure and temperature ranges are provided in the Technical Specifications in Section 2. This technical note is intended to further explain what atmospheric conditions are required. The TRANSPORT X detector is sensitive to the DGA diagnostic gases and it is this sensitivity that allows the unit to report ppm values for each of the seven gases. The instrument must first extract the gases from the oil prior to measurement. It employs the local atmospheric air during extraction of the gases from the oil and it is necessary, for measurement accuracy, that the ambient air does not contain any of the target gases. Local ambient gas above certain tolerances can reduce the instrument’s sensitivity to gas-in-oil. Measures have been taken to reduce this sensitivity and the instrument will report if it detects excessive gas in the ambient air. This will be in the form of an error report during instrument set-up or following completion of the analysis. If some local ambient condition is outside tolerance for the instrument, the software will offer suggestions as to action the user can take to minimize the effect of this contamination. Ideally the TRANSPORT X should be used in clean, outdoor or filtered indoor air, away from chemicals or solvents and away from sources of gas such as open containers of insulating oil to avoid any contamination issues such as those described above.
