Introduction
The on-load tap-changers 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.
