DTE-450/200 current injector

DTE-450/200 protection relays testing device


Protection relays testing device DTE–450/200 intended for:

·adjustment and testing of protection relays in places of their installation at power plants, substations, industrial plants or in the laboratory

·adjustment and testing of electroautomatics elements (electromagnetic relays, contactors, motor starters, etc.)

·adjustment and testing of circuit breakers

DTE-450/200 secondary current injector housed within a single enclosure, which creates additional convenience during use. It includes connecting wires and cables to connect testing objects.
