3 phase transformer on-load tap changer testeris mainly used to test three-phase transient time, transition waveform, transition resistance, synchronization state, etc. The transformer on-load switch tester is a comprehensive transformer on-load switch measurement and tester, which is used to measure and analyze the electrical performance indicators of power transformers and special transformers on-load tap-changers. The transformer on-load switch tester can automatically capture and display the transition resistance during the transition process. There is also a process of time jumping.
