The on-load tap changer is the only moving part connected to the transformer circuit. The HZYZ-2008 On-Load Tap Changer Tester is specifically engineered to measure the transition waveform, transition time, transition resistance values at each moment, and three-phase simultaneity of on-load tap changers in transformers.
