LOREM IPSUM \ IPSUM LOREM Circuit Breaker Test Equipment

BSG (Both Sides Grounded)

BSG feature enables safe and fast testing in high voltage substations, without removing the safety ground connections on both sides of the circuit breaker. No additional modules or remote boxes are required. Each main contacts timing channel is able to detect main contacts state in a case when both terminals are grounded.

First Trip Test

A “First trip” analysis is important to determine a condition of the coil operating mechanism. A circuit breaker spends most of its lifetime conducting a current without any operation. Once the protective relay detects a problem, the circuit breaker, that was idle for maybe a year or longer, has to operate as fast as possible. However, if the circuit breaker has not been operated for a long time, the latch friction may increase. Information about the latch friction can be obtained from the coil current waveform recorded during the “First trip” test.

Static Resistance Measurement

The built-in micro ohmmeter generates a true DC ripple free current with an automatically regulated test ramps. The resistance measurement is using the well known Kelvin’s four point’s method. The DC current is generated through the closed circuit breaker contacts. The voltage drop is measured between the terminals of the circuit breakers. The resistance is calculated using the Ohm’s law R=U/I.

DRM (Dynamic Resistance Measurement)

The built-in micro ohmmeter can also be used for the DRM. The DRM test is performed by injecting a current through the breaker contact and simultaneously monitoring the voltage drop across the breaker contact as well as the current flow during the operation of the breaker. Resistance curve as a function of contact travel can be used to reveal failures in relation to the arcing contact condition. The test current should be at least 100 A to provide a higher voltage drop to allow easier detection of the arcing contact. The DRM test requires the circuit breaker analyzer with a high resolution measurement.

Demagnetization of a Current Transformer Core after DC Contact Resistance Measurement

After a DC current test of a circuit breaker or bus-bars, the magnetic core of associated current transformers may be magnetized (remanent magnetism). To eliminate this source of potential problems, demagnetization should be performed. Following the apparatus resistance measurements, there is a possibility to start the demagnetization process using this instrument. The whole demagnetization process is performed automaticaly and does not require modification of any connections.


RMO-TW, TD and TT Series – Tap Changer Analyzers & Winding Ohmmeters The Winding Ohmmeters RMO-TT, -TD and -TW series are designed for the winding resistance measurement of inductive test objects (transformers/generators/motors) and for the on-load tap changer analysis of power transformers. Typical application areas of RMO-TT, -TD and -TW are high-voltage substations and industrial environments.

TWA30D – Tap Changer and Winding Analyzer

Tap-Changer & Winding Analyzer TWA30D is a one-of-a-kind diagnostic solution for power transformer testing. Using this device, the transformer testing is safer, significantly faster, and more convenient. The TWA30D instrument is designed for simultaneous three-phase tap changer analysis and six-winding resistance measurement of both the primary and the secondary transformer windings.

The measurement is obtained very quickly by saturating all three legs of the magnetic core at the same time. Once all 6-8 bushings are connected and the transformer configuration selected, the instrument adjusts the test procedure automatically. The TWA30D generates a true DC ripple-free current. The injection of current and the discharge of energy from the magnetic circuit are both automatically regulated.

Three-Phase Tap Changer Analysis

Dynamic resistance graphs are recorded for all three phases simultaneously, so the synchronization is verified using the cursors provided in the DV-Win software. All three phase traces are plotted on the same graph. In addition, the tap changer motor current is recorded, and displayed on the same graph. The measurement is completed quickly even on the largest power transformers. Each vector group has a special measurement algorithm which is optimized for the fast stabilization of test results.

Interchangeable Cables with the TRT63 Three - Phase Transformer Turns Ratio Testers

The test cables used for the measurement are completely compatible with the DV Power TRT63 instruments. This enables the user to measure, with a single connection of the test leads:

• Transformer turns ratio• Excitation current• Phase angle• Winding resistance in all tap positions• Dynamic resistance in all on-load tap changer transitions• On-load tap changer motor current• On-load tap changer transition time in all transitions• On-load tap changer transition ripples in all transitions• Transformer vector group

Automatic Three-Phase Demagnetization

The TWA30D instrument can perform three-phase demagnetization after the DC test is finished. The process is completely safe, fully automated and very fast. This enables the user to avoid problems such as high inrush currents at the start-up of power transformers, incorrect operation of protective relays, erroneous diagnostics or inaccurate electrical measurement on a transformer.

• Simultaneous three-phase OLTC dynamic resistance measurement and analysis, 3 x 10 A per phase• Rapid core saturation for fast secondary winding test• Total test current 10 mA - 36 A DC• Resistance measurement range 0,1 μΩ - 2 kΩ• All 6 windings measured in one test• Extremely quick measurement, the cable setup is performed only once• Typical measurement accuracy of 0,1%• Automatic discharge process• Rapid automatic demagnetization• AC current monitoring channel for tap changer motor current measurement• Built-in tap changer control unit

Using two sets of four cables, all bushings of HV and LV sides are connected at once. The connection to the transformer is made with two-contact clamps providing for four-wire Kelvin test method.




On-Load Tap Changer Analysis with DV Power Instruments

Due to their unique capabilities, the TWA30D and RMO-T series instruments are the best on-load tap changer analyzers in the market today. A tap changer analysis can be performed either by the stand-alone instruments, or in a combination with the DV-Win software. When used together with the DV-Win software, they enable the measurement of:

• Static resistance in all tap positions• Dynamic resistance in all tap transitions• On-load tap changer (OLTC) transition times in all tap transitions• OLTC transition ripples in all tap transitions• OLTC motor current

The TWA30D instruments enable simultaneous OLTC testing of all three phases in a single pass through the tap positions. In this manner, the total OLTC testing time is greatly shortened, by two thirds in comparison with the classic methods. This test procedure also enables observing the synchronization problems between the different phases.

The static resistance measurement provides winding resistance values on all tap positions for each of the three phases. There is no need to discharge the transformer between the measurements in different tap positions. The DV-Win software enables creating the static resistance graph from the results of the resistance measurement in different positions, as well as the automatic recalculation of the measured values to a reference temperature value. The shape of the static resistance graph depends on the winding regulation mode.

The dynamic resistance measurement (DRM) feature enables measuring and recording of the test current at high sampling rate during the tap change transition. The variation of the current represents the change of the resistance in the circuit during the change of the tap positions. Tap changer verification can be performed in the DV-Win software or on the stand-alone TWA30D or RMO-T instruments. The stand-alone instruments detect any open circuits during the tap changer operation.

The dynamic resistance measurement graph is unique, and above all, powerful tool that provides condition assessment of an OLTC regarding the mechanism itself and its contact wear. It is recorded by the DV-Win software. The innovative graph analysis tools enable the detection of:

• High resistance contacts in the tap selector• Loose contacts in the tap selector• Burned, loose contacts in the diverter switch• Broken resistors in the diverter switch• Abnormal arcing• Misaligned contacts• Contact bounce • Mechanical and motor problems • Phase synchronization problems

The AC current monitoring channel enables monitoring and recording the OLTC mechanical-drive motor current during the tap changer operation. The motor-current waveform is also printed on the same DV-Win-generated graph, and can help in detecting OLTC mechanical problems.

The OLTC transition times, as well as the percentage of a current drop during transitions (known as the transition ripples), are recorded numerically. The DV-Win software records these values in the Test Report together with the static winding resistance values. It is possible to save the Test Report in various formats, such as PDF, XLS, DOC, etc.

TRT Series – Three-Phase Transformer Turns Ratio Testers The TRT is a true three-phase, fully automatic test set, specially designed for a turns ratio, a phase shift and an excitation current measurement of power, distribution and instrument transformers. The TRT determines the transformer turns ratio by accurately measuring the voltages across the unloaded transformer windings. Following these measurements it displays the ratio of these voltages.

All the TRT devices are equipped with a tap changer control unit which allows changing tap positions remotely. USB Flash Drive feature enables saving all the test results to a USB memory stick. DV Power provides 112 mm built-in thermal printer as an option.

Setting up the TRT is as simple as connecting it to de-energized transformer and entering the transformer configuration using the device front panel keyboard. Once the parameters are selected, the test of the three-phase transformer is performed in one of the two ways:

SINGLE-PHASE – Three single-phase voltages are applied to the three transformer primary windings, and all three phases are measured consecutively (phase by phase). All connections and short circuit procedures at the primary and secondary voltage terminals are automatic, done internally before each measurement, depending on the selected vector group.

TRUE THREE-PHASE – A true three-phase excitation voltage is applied to the three transformer primary windings. Three induced phase voltages are measured at the same time. In such a way it is possible to detect the phase angle and measure the turns ratio of any transformer type, including phase shifting transformers, where other “three-phase” turns ratio testers cannot.

Main Features

• Ratio range 0,8 – 50 000 • Test voltages 1 V to 250 V AC• Measurement of turns ratio• Measurement of phase shift• Measurement of excitation current • Vector group detection• Built-in thermal printer
