The Transformer On-load Tap Changer Switch Parameter Tester is the only moving part which is connected with the circuit of the transformer, so more and more attention has been paid to the detection of the on-load tap-changers. The instrument is mainly used to measure the transition waveform, the transition time, the transient resistance value, the three-phase synchronization of the transformer on-load tap-changers.
