HDYZ Transformer On-load Tap changer Tester

General Information
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.     
● 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
