AL110On-load tap-changer tester
Implementation of standards.
DL/T846.8-2004
It is a comprehensive test equipment which is used to measure and analyze electrical properties index of on-load tap-changer of power transformer and special transformer in power system and has the function of analyzing, saving and printing test data. Controlled by computer, it can realize auto measuring of parameters such as transition time, transition waveform, transition resistance, and three-phase synchronism of on-load tap-changer through specially designed measuring circuit, so that user can not only measure via tap-changer lead, but also carry out measuring through direct wiring of three-phase sleeve of transformer and neutral point according to needs and site condition. It is of vital importance in improving reliability of power system operation when promptly diagnosing latent fault of tap-changer in preventive test of power equipment and transformer overhaul, solving the problems of test method of on-load tap-changer of power transformer outdated and undedicated.
