1 phase relay test set

I.Trosolwg

This instrument is a new type of high and low voltage power distribution system for single phase protection relay verification. The design basis of performance and test method is: "new protection relay inspection" compiled by the safety supervision and production coordination department of the ministry of electric power industry. Suitable for electric power, metallurgy, chemical industry, mining, textile and other industrial and mining enterprises. It can test and verify the action voltage/current value, return voltage/current value, action time, return time and the action value, return value, charge and discharge time, action time of all kinds of electromagnetic type, rectifier type, transistor integrated circuit type relays. It can also be used to test the starting current, the operating current of the sensing element, the operating current of the quick-break element and the operating time of the GL and LL reverse time relay.
