The instrument is a variety of high and low voltage power distribution system, as a new type of single-phase protection relay calibration equipment. Performance and test method of the design basis is: the Ministry of power industry safety supervision and coordination of production our compile the new protection relay test. Applicable to electric power, metallurgy, chemical industry, mining, textile and other industrial and mining enterprises. But on all kinds of electromagnetic type, rectifier and transistor integrated circuit relay action voltage / current value, return voltage / current value, action time, return time and reclosing relay action value, return value, charge and discharge time, action time etc. for testing and calibration. Can also be of GL and ll type anti time limit relay initial current, the action current of the induction element and quick break element operating current and operating time were tested.
The instrument to protect relay check the current generator, a voltage generator, electric stopwatch, standard voltage / current meter, voltage regulator and so on a series of electrical equipment, scientific combined into a complete portable instrument, the analog standard voltage / current meter, electric stopwatch changed to standard digital table, accurate readings, the operation is simple, is the ideal testing instrument for calibration of protection relay.
The utility model has the characteristics of high precision, large power, small volume, light weight, simple and convenient operation, complete functions, reliable performance, convenient operation, high reliability, convenient operation, and convenient operation.
