What tests should do for transformers in field?In order to ensure that transformer can function properly in fieldthe following tests should be performed:1) Transformer Temperature test: Temperature is a key factor to help judge whether transformer is running well or not. The upper oil temperature m

CT Analyzer Operation introductionCT Analyser is also called CT parameter analyzer, mianly used for testing excitation parameters for current transformer (CT), voltage transformer (PT), including: turns ratio, turns ratio error, polarity, coil resistance, ratio and angularity checking, ect. CT Analy

Transformer turns ratio measurementGenerally judging the quality of a transformer requires the following tests: AC withstand voltage, DC resistance, turns ratio, capacity, Load and no-load loss. For the turns ratio test, it is mainly to measure the actual transformer turns ratio error. The nameplate
