Protective relay calibrator SRT-193
This instrument is a new type of instrument for calibration of single-phase Protective relay in various high and low voltage distribution systems
Classification：
Protective relay test instrument
Product description
This instrument is a new type of instrument for calibration of single-phase Protective relay in various high and low voltage distribution systems. The design basis of performance and test method is New Protective relay Inspection organized by Safety Supervision and Production Coordination Department of Ministry of Electric Power Industry. Suitable for industrial and mining enterprises such as power, metallurgy, chemical, mining, textile, etc. It can test and verify the operating voltage/current value, return voltage/current value, operating time, return time of various electromagnetic, rectifier, and transistor integrated circuit relays, as well as the operating value, return value, charging and discharging time, operating time, etc. of reclosing relays.
This instrument scientifically combines a series of electrical equipment such as current generator, voltage generator, electric stopwatch, standard voltage/Ammeter, Pressure regulator, etc. used in the calibration of Protective relay into a complete portable instrument. The analog standard voltage/Ammeter and electric stopwatch are changed into digital standard meters. With accurate readings and simple operation, it is an ideal test instrument for Protective relay calibrators.
