Product Overview
The on load tap changer is a moving component connected to the transformer circuit, so the detection of on load tap changers is becoming increasingly important. In the "Regulations for Handover and Preventive Testing of Power Equipment", it is required to check the sequence of action of on load tap changers, measure switching time, etc. This instrumentTransformer on load tap changer testerMainly used to measure the transition waveform, transition time, instantaneous transition resistance values, three-phase synchronicity, etc. of on load tap changers in transformers.
