Ⅰ: Description of the single phase relay tester:
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 characteristics of the instrument: high precision, large power, small volume, light weight, digital display, simple operation, complete functions, reliable performance, convenient and durable.
