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. According to the industry standard DL/T846.8-2004 Load tap changer tester, it is required to check the action sequence of the load tap changer, measure the switching time, etc. For this purpose, our company has successfully developed this tester, which is mainly used to measure the transition waveform, transition time, instantaneous transition resistance value, three-phase synchronicity, etc. of on load tap changers in transformers.
