TPI – Over / Under Voltage Protection

Over and Under voltage Protection Relay, Measurement and Communications

Overvoltage and under voltage protections are usually inverse or definite time type, with tripping times between 0.2 and 20 s. Instantaneous trip is required in those cases where the magnitude of the overvoltages is considerable. TPI protective relays, are applicable in those installations requiring a reliable detection of voltage fluctuations.

Key Features

  • Single and Three Phase Over/Under Voltage Protection.
  • Ground Overvoltage Protection.
  • Serial Ports for Remote Communication (electric and fiber).
