I.Overview

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.

The instrument used in the protection relay calibration current generator, voltage generator, electric stopwatch, standard voltage/current meter, voltage regulator and a series of electrical equipment, scientifically combined into a complete portable instruments, the analog voltage/current meter, electric stopwatch to digital standard table, reading precision, simple operation, is protective relay check personnel ideal test equipment.

Features: high precision, large power, small volume, light weight, digital display, easy operation, complete functions, reliable performance, convenient and durable.
