The DTE–450/3000 device purpose

Relay Protection Testing Device DTE–450/3000 (hereinafter – device) is intended for

  • adjustment and testing of simple relay protection (RPA) in place 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

The device is implemented within single body, which creates additional convenience during use. It includes connecting wires and cables to connect testing devices.
