Performance tester HDYZ

for transformers

HDYZ Transformer on-load tap changer Tester is a unique moving part that is connected with the circuit of the transformer, It is essential to test the on-load tap changer of action sequence and switching time. HDYZ Transformer On-load Tap Changer Tester is mainly applied to measure the  transient waveform,  transient time, transient resistance value, three-phase synchronization of transformer on-load tap-changers.        Features   ● The tester can output large current and be light to carry . ● Two output current with wide measurement range and high stability. ● It automatically calculate transient resistance value and transition time ; ● With perfect protection circuit and high reliability; ● 5.7 inch large LCD display, easy for on-site operation ● With U disk storage function for storing more data and waveform ● It is more efficient and convenient for operation by independent keyboard
