1. PURPOSE

The purpose of this procedure is to test and document the integrity of cables, metal enclosed bus duct, and switchgear assemblies of both 4.16kV and 13.8 kV levels using an ac/dc source.

2. SCOPE

This procedure applies to both ac and dc high-potential testing. DC high-potential testing is preferred for testing on a periodic basis since it is more than a "go" or "no-go" test, as is the ac test. The dc test can indicate that the tested object is all right at the present time but may fail in the future. The ac high-potential test is more accepted standard in practice.

3. REFERENCES

3.1. IEEE Standard 62-1958, IEEE Recommended Guide for Making Dielectric Measurements in the field.

3.2. The ac high-potentla1 test levels recommended by the national standards ANSI for switchgear assemblies and rigid bus.

3.3. The ac/dc high-potentla1 test levels recommended by IEC 60502 standards for 1kv to 15 kv cables

4. NOTES AND PRECAUTIONS

4.1. Due to high voltage being used, adequate safety precautions should be taken to avoid injury to personnel and damage to property.

4.2. Always use approved and tested safety rubber gloves when connecting and disconnecting test leads to and from the apparatus, and while operating the test equipment.

4.3. Test equipment operation shall be in accordance with the manufacturer's instructions.

4.4. In the case of unshielded cable, the non-uniform electric field between conductor and the metal enclosure (ground) may introduce excessive stresses in the insulation. In the case of unshielded cable it is therefore recommended that a dc test only be carried out.

4.5. Shielded power cables require electrical stress control when they are terminated. Cables shall be made up with either stress cones or with heat-shrinkable stress control material.

4.6. The cable route or the equipment should be walked down to establish safety boundaries as necessary for personnel and equipment protection.

4.7. Ensure that all voltage transformers are disconnected for the duration of the test and that all current transformers are short-circuited.

4.8. Continuity and phasing of all cables and switchgear bus-work should be checked, where

practical.

4.9. Provision should be made to ground equipment through a resistance by means of a hot stick after megger or high-potential testing.

4.10. Ensure that all cable shields and switchgear grounds have been made per the installation instructions.

4.11. Conductors of each like phase may be tested together, provided the source has adequate capacity to maintain the specified test voltage for the required period of time. Conductors not being tested shall be tied together, using a soft wire and grounded at the test end.

4.12. Phases should be properly identified and labeled

4.13. This test should be performed only by personnel who are properly trained on the test equipment. Safety rules, testing procedures and interpretation of the results.

5. PROCEDURE

5.1 Determine the test voltage, kVA and times and voltage steps to be used (refer to Appendix A).

5.2 De-energize, discharge and safety) tag the cable/equipment to be tested, as necessary. Record the scheme/cable/equipment number on the High-Potential Data Record form.

5.3 Disconnect the cable/equipment from the equipment/cables at each end and position it with maximum possible clearance from objects. The minimum clearance recommended to preclude flashover is 10 cm. Ensure that open cable ends are insulated.

5.4 Ground all equipment, cables and conductors not under test that are in contact with the cable under test or that can become energized by a flashover.

NOTE

Where high-potential testing of shielded cables with grounded shields is to be performed, the existing cables/equipment need not be grounded.

5.5 As a precautionary measure a 2,500 V megger reading shall be made between the test terminals to ensure that the equipment/cable is free from gross defects as a result of damage during installation and that no inadvertent grounds have been left. The megger readings should be recorded on the High-Potential Data Record form.

NOTE Megger resistance values will vary over a wide range depending on the type of equipment being tested and the test environment. As a result it is difficult to state precisely what constitutes an acceptable megger resistance value. However, as a general rule, tests should be terminated if the insulation resistance is less than 5 Mohms for 5 kV class equipment and 15 Mohms for 15 kV class equipment. Abnormally low values of insulation resistance should be

investigated before proceeding further with any test

5.6 Position the test instrument inside the test area keeping the high voltage lead between the test instrument and the cable/equipment being tested.

5.7 Connect the test set in accordance with the manufacturer's instructions.

5.8 Set the ammeter to its highest range.

5.9 Set the voltage to its lowest range.

CAUTION

Avoid overshooting the voltage. The initially applied direct-current voltage shall not be greater than three times the rated alternating-current voltage of the cable for high-potential dc testing.

5.10 Gradually increase the test voltage until the desired test level is reached. During the voltage buildup, the rate of increase of the applied voltage shall be approximately uniform so that the required time shall be no less than 10 seconds and no more than 60 seconds for dc high-potential testing and shall not exceed 10 seconds for ac high-potential testing.

NOTE If cable/equipment insulation failure should occur as indicated by the high ammeter reading, secure the test voltage immediately.

5.11 Measure leakage current at the end of each step, record data on the High-Potential Data

Record form.

5.12 Repeat steps 5.10 and 5.1 1 correcting any abnormalities, until the maximum test voltage is reached.

5.13 Maintain maximum test voltage as indicated in Table 3 of Appendix A. Measure leakage current every minute and record data on the High-Potential Data Record form.

5.14 Reduce test voltage continuously, but not abruptly

5.15 Turn off the test instrument and allow the voltage to decay for the minimum time in accordance with the test instrument instruction.

CAUTION

A dangerous charge may be stored by the apparatus unless it is grounded after the test.

5.16 Ground the cable/equipment (use a discharge rod) and allow the ground to remain in place for a period of at least 3 to 5 minutes.

5.17 Remove the test connections.

5.18 Restore the cable to its as-found condition.

5.19 Remove all grounds installed in Step 5.4. 6. ACCEPTANCE CRITERIA

The equipment tested shall withstand the imposed potentials for the prescribed periods of time without distress or failure.

NOTE

If the leakage current versus voltage are plotted as a curve, as long as this plotted curve is linear for each step. The insulation system is in good condition. At some value of step voltage if the leakage current begins to increase noticeably an increase in the slope of the curve will be noticed. as shown in the figure below. If the test is continued beyond this test voltage, the leakage current will increase even more rapidly and immediate breakdown may occur in the cable insulation.

When the final test voltage of leakage current versus voltage test is reached, it can be left on for the required time and the leakage current versus time can be plotted for fixed intervals of time as the leakage current during this step reduces from an initial high value to a steady-state value. A curve for good cables will generally indicate a continuous decrease in leakage current with respect to time or steady-state value without any increase of current during the test. This is shown in the figure below.

The high voltage DC shall be applied to each individual cable of a 3-phase circuit. All cable conductors and shield not on test shall be grounded. High voltage DC test shall be as per IEC 60502 that is 4XU0 for 15 minutes. OR 1.7[.75(2 X equipment maximum voltage + 1kV)] for 15 Minutes (ARMCO) The test connections are as shown in figure 5-3. A DC high potential test (controlled over voltage test) is one in which the increase of applied direct voltage is controlled. The measured current is continuously observed for abnormalities with the intention of stopping the test before breakdown occurs The initially applied voltage shall not exceed 1.8 times the rated AC phase to phase voltage of the cable. After that the rate of increase of the test voltage shall be approximately uniform and shall not more than the maximum test voltage in 10 seconds or less than the maximum test voltage in 60 seconds. The maximum test voltage shall be maintained for 15 minutes, leakage current shall be recorded in TS-CMO2. No breakdown of the insulation shall occur.

5.2.2 CT Ratio Test By Primary Injection/ Phase Angle Error

5.2.2.1 CT Ratio • Current ratio test can be done by injecting current in primary circuit

and measuring the current at secondary by Primary injection test set as per following schematic diagram

• Check the CT ratio by injecting current as much as near to normal current of the CT primary and measure the corresponding secondary current.

• The test is to be carried out individually for each core and phase. Use precision clamp meter and Ammeter to measure the primary and secondary current respectively Ratio test CPC100

5.2.5 CT Polarity Test.

CT polarities can be checked by using 9 volts battery and a zero center galvanometer as per the following Schematic Drawing

On pressing the switch momentarily in above circuit, the needle on center zero galvanometer or sensitive ammeter reads positive deflection thus polarity of the transformer is subtractive. Subtractive polarity exists when current going into the primary polarity terminal causes to go out of the secondary polarity at the same instant in time Polarity Test by CPC 100.

5.2.6 CT Burden Test

CT Burden test can be done by a variable voltage source with voltmeter and ammeter as per schematic diagram • The burden in each core of each phase is determined by injection

of a current of 1 A (or 5 A as appropriate) in the direction of the load and measurement of the voltage with respect to earth. The




: : :

voltage across the burden must decrease on moving from burden to burden along the current path. The measured burden should be compared with the rated data of the current transformer.

Burden measurement by CPC100

5.2.7 CT Magnetization Current test

CT Magnetization test can be done by a variable voltage source with voltmeter and ammeter as per schematic diagram




: : :

SEC-COA BEMCO


“10621166/00”


• Apply the voltage gradually in 10% increment of the knee voltage and note down the secondary excitation current

• Current values are obtained for every 10% voltage increment till the knee point. Knee point is the condition where 10% increase in voltage results in 50% increase in current

• Minimum two points over the knee point and five points below the knee point shall be taken.

• Readings are tabulated on a excel from where a graph is generated automatically Magnetization curve By CPC100

5.2.8 Demagnetising the CT Core

After performing the above tests, a voltage greater than knee voltage shall be applied gradually to CT secondary and reduced slowly back to zero. CPC 100 can also be used for demagnetising the CT core

5.2.9 Inter Core Coupling Test for Bus Differential CT’s

In many instances several secondary windings are mounted in close proximity on the same primary lead. It is possible, through failure of grading shields or support structures, to have coupling between cores which is not detectible by excitation tests, but it is still substantial enough to improperly operate bus differential relays. The presence of abnormal coupling can be detected by reading open circuit voltage on CT's adjacent to a CT being excitation tested. By measuring the voltage across the secondary of differential CT’s when adjacent core is excited during magnetisation current test.


• CT’s are subject to high voltage tests during High voltage test of switch gear.

• While performing high voltage test CT secondary should be isolated from load and kept shorted/grounded

5.2.11 Verification of Secondary Circuits , Terminals shorting /Isolating Links by Primary Injection During primary injection check secondary circuit terminal shorting/isolation is working properly by closing the shorting slid link and opening the slid link, there should not be any current in direction of load.

5.2.12 Phase Identification Test Check phase identification by injecting primary current in single phase Check the current in all the three phase. Two phases should read zero current and third phase whose primary has a current should read a secondary current

5.2.13 Checking the Protective Earthing and Single Point Earthing Current transformers must be earthed on the secondary side in order to afford protection to human beings. In order to avoid circulating currents such earthing is permissible at one point only of a metallically connected system. (In case of physical separation of the phases the three earthing points should be regarded as being one earthing point.) Meeting of both requirements is verified in a simple manner by opening of the earthing point link and connection thereof to a secondary testing device while simultaneously measuring the current I=0. Subsequently the earth connection is to be restored.

6.0 Documents Test Sheet TS-CT01 shall be completed for each set of instrumentation transformers.

All the test results shall be entered in the test form No.TS-CT01of the transformer. Refer TP-CT01 for the test procedure

5.3.15. Sweep Frequency Response Analysis Sweep frequency response analysis is tool which gives an indication of winding or core movement, deformation of winding axial or radial, spiraling short or open turns etc. The test can be performed by using DOBLE M5100 test equipment (please refer M5100 manual for test procedure). Test results are stored as a baseline reference and can be verified with results obtained during factory testing or can also be verified with the results of sister transformer in case factory results are not available. The test can also be performed once the transformer arrives and bushings are connected with no oil, provided no combustible gas in. This gives confidence in the mechanical integrity of the unit prior to further work and commissioning.

5.2.1 Electrical Function Test 5.2.1.1 Functional check of Test Plug

Test Plug should be checked for its correct function, terminals should be checked for its correct current, auxiliary power and tripping assignment as per the circuit drawing.

5.2.1.2 Shorting of links on relay case when Relay is Withdrawn In case of withdrawal type relay, shorting facility on the relay case should be checked as under. • Connect the fluke to check the continuity across the current terminal on

the relay case and it shows some resistance. • Pull the relay out and check the fluke which shows now resistance less

then when relay was inside. • Repeat the test for other two phases too.

5.2.2 Secondary Injection Connection between the relay and secondary injection set is made as per figure below.

5.2.2.1 Relay Power Measurement • Apply rated DC or AC auxiliary voltage to the power terminal of the relay

through suitable ammeter and voltmeter • Measure the current and voltage. Product of two gives power consumption

of the relay.

5.2.2.2 Configuration of the Relay Relay should be configured for inputs, outputs, and LED assignment as per final setting either through front panel of the relay or through lap top communicating with relay.

5.2.2.3 Testing of LEDs • Check the operation of LEDs first by pressing reset button, all the LEDs

should light for 2 to 3 seconds • Check the operation of LEDs for their function by injecting current or by

simulating the software.

5.2.2.4 Testing of out put Relays • By simulation or by performing secondary injection, check the operation of

output relays as per the relay configuration. • Measure the contact resistance of the each output relay with fluke

5.2.2.5 Testing of Digital Inputs • Connect a variable auxiliary DC or AC voltage to each and every Digital

input • Increase the voltage till the digital input picks up (a temporary LED may be

assigned to see the pickup) thus a minimum voltage required to operate digital input is noted.

5.2.2.6 Metering Function • Configure the relay for Phase CT and neutral CT ratio. • Apply three phase 25%, 50%, 75% and 100% of nominal current on phase

over current relay and note down the corresponding readings on the relay. • Apply Single phase 25%, 50%, 75% and 100% of nominal current on

4.6. Testing of Grouped Element

4.6.1. Transformer Differential Setting / Grouped Elements / Group 1 / Transformer/percent differential TRANSFORMER DATA: 110 MVA, 380/13.8 kV, CT (HV) = 600:1, CT (LV) = 6000:1, Yn/d1d1 OPERATING CRITERIA: The differential element operates if the differential current (Id) exceeds the characteristic defined by the relay settings for restraint current magnitude (Ir) The differential current Id is the vector sum of the compensated currents, and Ir is the largest compensated current. Compensation refers to vector and magnitude corrections applied to the currents from the HV and LV transformer sides. The tests verify the operation and no-operation response for points from all regions of the percentage differential characteristic. These tests are:

• Test for zero differential current • Minimum Pickup • Slope 1 • The region between Slope 1 and Slope 2 • Slope 2 RELAY CONFIGURATION: NOTE: WARNING: APPLICATION OF EXCESSIVE CURRENT (> 3 x In) FOR EXTENTED PERIODS WILL CAUSE DAMAGE TO THE RELAY!

Inject currents into the relay as shown in the table below until the biased differential element picks up. 3. Confirm that only the percent differential element has operated. 4. Increase the harmonic content until the element drops out. Record this value as the Inrush Inhibit Level Pickup. 5. Gradually decrease the harmonic content level until the element picks up. Record this value as the Inrush Inhibit Level Dropout. 6. Switch off the current. 7. Repeat steps 1 through 6 for phases B and C. 8. Repeat steps 1 through 7 for Winding 2 and Windings 3.

1. Task This instruction comprises a complete description of the testing of Batteries

2. Preconditions 2.1. Work Satus


been carried out.

2.2. Documentation • The single line diagram for the battery system, charger schematic drawings • Test Sheet TS-BT01 is available • Product manual of the Batteries

2.3. Personnel • Commissioning engineer: - (1) engineer with experience in commissioning of

Battery and Chargers usually • Technician or helper:- (2) skilled worker with adequate on -the-job training • Witness from the client‘s concern department


• Multi meter (calibrated)—2 • Clamp Meter DC(calibrated)—1 • Hydro Meter to Check Specific Gravity • Battery Tester • Load Bank up to 300 Amps

3. Precautions The work will only proceed when a Permit to Work (PTW) in work permit area has been obtained. The PTW will be kept on site for consultation during the testing works. • Special safety arrangements shall be made for all areas which are not explicitly



• Nickel Cadmium Batteries contain a corrosive alkali causing chemical burns if it comes into contact with skin or eyes. Eye wash and safety facilities must be in place prior to any work on the batteries. Also operators working on batteries must wear protective clothing like rubber, gloves, face mask, etc. and eye protection and use insulated tools and correct working techniques, which forbids lone working.

• As part of the charging cycle the cells will give off hydrogen gas. Hydrogen/ Air mixture is an incendiary mixture that can be ignited by electrical sparking/ arcing / naked flame. For this reason correct ventilation of cells and the battery room is essential to prevent the build up and ignition of hydrogen / air mixtures.




: : :

SEC-COA BEMCO


“10621166/00”


4. Scope

• Testing of Batteries • Checking that the mounting, • Testing of Cables • Checking of correct Earthing,


Prior to carrying out electrical tests, a visual check of the transformer should be carried out paying particular attention to the following points • Correct labeling of devices and cables • Equipment and cables are undamaged • Correct execution of the cable gland/sealing end • Name plate data, match with drawing and ambient condition • Firm cable termination/terminal connection and ferruling • Battery Rack is in good condition • Vent Plugs are Installed correct • Inter-cell Connections are checked and torque • Electrolyte Level in all cells is correct • Battery and Bus are free of grounds • Battery Room has Proper Ventilation and in service

5.2. Testing of Batteries Following tests to be carried out

1. Torque for the battery inter-cell connection 2. Battery Internal Resistance Measurement 3. Battery Initial Charging 4. Battery Discharge Test 5. Protective Earthing

5.2.1. Torque for the Battery Inter-Cell Connection

Tightness of the bolt on inter cell connection shall be checked and torque to the value recommended by the manufacturer.

5.2.2. Battery Internal Resistance Measurement Battery internal resistance can be measured by the battery tester

5.2.3. Battery Initial Charging For those batteries which were delivered pre-filled perform a new or initial commissioning charge with a constant Voltage at 1.63V/Cell for duration of 20 hours with a current limit to 0.2itA and electrolyte temp within 20 degC with Specific Gravity of 1.19-1.22. If the charger has a limit to deliver the charging current, then duration for charging to meet 100% battery capacity can be calculated by Battery 2*Ah * 1.63/Charging current




: : :

SEC-COA BEMCO


“10621166/00”


Cell voltage gradually rises with progress of the charging, so that it is necessary to raise the rectifier’s output voltage accordingly by means of its manual output voltage regulator in order to maintain the charging current constant at the specified rate

When the charging is to be carried out online where charger is supplying power to the load as well and the voltage can not be controlled. The charging shall be done on a part of the bank at a time, say half the bank (48 cells) per charge. Also, if the discharge test fails the first time, then a second test shall be done after another commissioning charge. After Constant charging the batteries shall be kept on float charging at the rate 1.43/cell for at least 1 hour.

5.2.4. Battery Discharge Test

Ensure that all the preliminary tests listed above are completed. Also ensure that the battery has been fully charged to 100% Capacity before the discharge test start. The discharge test shall be made on each individual battery bank. The duration of the test is five hours and the discharge current shall be the battery AHr capacity divided by 5. The voltage per cell at the end of discharge shall be at least 1.0 Volt(or as per Manufacturer’s data). This is true for cells which are 5 hour rated. For cells which are 8 hour rated, the discharge time may be less than 5 hours and this has to be taken into consideration while interpreting the results. The step by step procedure is as follows:

• Open battery disconnect switch or disconnect battery supply cable from 125 volts terminals of the charger.

• Connect battery discharge resistance bank, but leave open circuit. • Measure and record individual cell voltage and ensure each cell is

within tolerance as stated in 5.2.3,

• Record Individual cell specific gravity, and temperature of electrolyte

• Put on load which is equal to 0.2C; Take the readings of cell voltage, specific gravity for 1st, 2nd, 3rd, 4th and every 15 minutes after 4th hour till 5th hour.

• At the end of the test, total battery voltage is recorded
