On-Load Tap Changer Tester Manufacturer
Darui Electric recommends for you:
The On-Load Tap Changer Tester is based on the "Power Equipment Handover and Preventive Test Procedures" and adopts testing principles. Using microcomputer technology, it can test the performance of on-load tap changers of various power transformers without disassembling the transformer or lifting the tap changer, and display and print the waveforms and parameters of the transition process. It is a power instrument. 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 or from the transformer's three-phase bushings and neutral point as needed.
