Xtester-ZWJD101 Single Phase Relay Tester
Overview
The instrument is a variety of high and low voltage distribution system, as a single - phase protection relay calibration of the new instrument. The design basis of performance and test method is: new protection relay inspection compiled by safety supervision and Production Coordination Department of ministry of Electric Power Industry. Suitable for electric power, metallurgy, chemical, 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 action value, return value, charge and discharge time and action time of reclosing relay of various electromagnetic type, rectifier type and transistor integrated circuit type relay. It can also test the starting current, induction element action current, quick break element action current and action time of GL type and LL type reverse time limit 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 the operation is simple, accurate, It is an ideal test instrument for protection relay calibrator. The characteristics of the instrument: high precision, large power, small volume, light weight, digital display, simple operation, complete functions, reliable performance, convenient and durable. |
