This instrument is a new type of instrument used for calibration of single-phase protective relays in various high and low voltage power distribution systems. The basis for the design of performance and test methods is: "New Protection Relay Inspection" compiled by the Department of Safety Supervision and Production Coordination of the Ministry of Electric Power Industry. It is suitable for industrial and mining enterprises such as electric power, metallurgy, chemical industry, mining, textile and so on. The operating voltage/current value, return voltage/current value, operating time, return time, and the operating value, return value, charging and discharging time, and operating time of various electromagnetic, rectifier, and transistor integrated circuit relays can be measured Wait for testing and verification. It can also test the starting current, inductive element operating current, quick-break element operating current and operating time of GL and LL type inverse time relays.
This instrument scientifically combines a series of electrical equipment such as current generators, voltage generators, electric stopwatches, standard voltage ammeters, voltage regulators, etc. used in the calibration of protective relays into a complete portable instrument. The voltage/current meter and the electric stopwatch are changed to digital standard meters, with accurate readings and simple operation. It is an ideal testing instrument for protective relay checkers.
The characteristics of this instrument: high precision, high power, small size, light weight, digital display, simple operation, complete functions, reliable performance, convenience and durability.
