OLTC.100A On-load tap-changer tester
About the OLTC.100A:
-
The on-load tap-changer is the only moving part that is connected to the transformer circuit, so the detection of the on-load tap-changer is getting more and more attention.
-
In the "Procedures for Handling and Preventive Tests for Electrical Equipment", it is required to check the sequence of actions and the switching time of the on-load tap-changer.
-
The OLTC.100A on-load tap-changer tester is mainly used to measure the transition waveform, transition time, transient resistance value, and three-phase synchronization of the on-load tap-changer.
