GDB-IV Transformer Turns Ratio Tester is suitable for measuring variable ratio phase of power transformers, phase-shift rectifier transformers, Scott transformers, reverse Scott transformers, etc.The internal power module in the tester generates the three-phase power or two-phase power, which is out

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
