The On-load Tap Changer Tester is a power instrument that, based on the "Regulations for Handover and Preventive Tests of Power Equipment", adopts testing principles and uses microcomputer technology. Without disassembling the transformer or lifting the switch, it can test the performance of on-load tap changers of various power transformers, and display and print the waveforms and their parameters during the transition process..The tester is a comprehensive measuring instrument used to measure and analyze the electrical performance indicators of on-load tap changers in power transformers and special transformers in power systems. It uses computer control and a specially designed measuring circuit to measure parameters such as transition time, transition waveform, transition resistance, and three-phase synchronization of the on-load tap changer. It can be measured directly from the tap changer leads as needed, or by direct wiring from the transformer's three-phase bushings and neutral point.
