It is mainly used for measuring the transition waveform, transition time, transient resistance of transformer on-load tap changer, three-phase synchronism, etc
Note:
Regarding product purchase, technical maintenance and other services, welcome to send email:
The on-load tap changer is the only moving part connected with the transformer circuit, so more and more attention has been paid to the detection of the on-load tap changer.In the electrical equipment handover and preventive test regulations, it is required to check the action sequence of on-load tap changer, measure switching time, etc.This device is mainly used for measuring the transition waveform, transition time, transient resistance of transformer on-load tap changer, three-phase synchronism, etc.
product names：On - load tap - changer tester, transformer on - load tap - changer tester, transformer on - load switch tester
