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.

3 Phase Transformer On-load Tap Changer Tester

Feature ：

1. The transformer on-load tap changer tester has good anti-interference performance. The all-aluminum alloy case and the tester are equipped with power supply noise filters and anti-interference circuits, which can be used in poor power supply and strong electromagnetic field interference. Reliable measurement on site, direct display of resistance value; automatic analysis of waveform failures and mark failures. Automatically adjust the resistance value and time range according to the sampled data
