Transformer Ratio Automatic Testing Instrument

Introduction to the Automatic Transformer Ratio Group Test Instrument

ED0203BThe Transformer Ratio and Group Test Instrument, also known as the Transformer Transformer Ratio and Group Test Instrument, is an ideal testing device for power system and transformer manufacturers, as well as railway electrical systems, to conduct transformer ratio tests, group tests, polarity tests, and angle tests. This transformer ratio and group test instrument automatically generates a stable amplitude and constant phase three-phase, two-phase, or single-phase standard power supply.

This transformer ratio and group test instrument automatically generates a stable amplitude and constant phase three-phase, two-phase, or single-phase standard power supply.ED0203BTransformer Ratio Group Test Equipment is suitable for the testing of three-phase transformers in power systems.ZScott-type, reverse Scott, and balanced transformers for type winding transformers, rectifier transformers, and railway electrical systems can accurately measure turns ratio and error.ED0203BThe Transformer Ratio Group Tester features a large LCD screen, full Chinese menu, and Chinese character printing output. It is a comprehensive and user-friendly instrument, ideal for power systems, transformer manufacturers, and railway electrical systems to conduct transformer ratio, group, polarity, and phase difference tests.

 ED0203BThe Transformer Ratio Group Test Instrument inputs single-phase power supply. It internally uses a power amplification module to generate three-phase power output to the high voltage side of the transformer. The low voltage side samples the data, which is then processed and displayed on the main unit. It can perform tests on the ratio, error, group, or phase angle of conventional three-phase transformers or other special transformers. Additionally, this test instrument can provide a set of phase difference.90The dual-phase power supply output is capable of testing transformer ratio and phase difference for inverse Scott transformers, widely used in intelligent sub-stations for new power equipment.

Product Features

1The Transformer Ratio Group Test Instrument automatically generates a stable amplitude and constant phase three-phase, two-phase, or single-phase standard power supply.

2Unrestricted by the internal wiring method of the transformer, directly measure the voltage ratio and phase angle difference between the high and low voltage sides.

3Efficient and swift, the testing of a set of data takes just a few seconds, and it can transition tap changers during the process, completing the measurement of all tap positions on a transformer in one seamless operation.19The testing time for tap-changer transformers is only10In mere minutes, efficiency is greatly enhanced.

4Our internal design features an overcurrent protection function.

5Test results are unaffected by fluctuations in the frequency and amplitude of the power supply frequency.

6Especially suitable for the ratio and phase difference testing of special transformers.
