HTCT Transformer On-load Tap Changer Tester

HTCT Transformer On-load Tap Changer Tester

HTCT Transformer On-load Tap Changer Tester Brief Introduction:

It is an integrated instrument used for measurement and analysis power transformers and special transformers on-load tap changer’s electrical performance of power system. It adopts computer-controlled, through a specially designed measuring circuit can be realized measurement of on-load tap changer’s transition time, transition waveform, the transition resistance, three-phase simultaneous performance and other parameters. According to the user’s needs and field conditions, it not only can directly lead measure from tap changer, but also can use the transformer three-phase bushing and the neutral point lead measure directly.
