ORION Protection Relay (SMPR)

ORION  Summarize Measurement and Protection Relay

The SMPR-1 has been designed to measure the line and the ground RMS currents and supply RMS voltages, under normal conditions or under disturbances. This information is internally processed by the microprocessor, to take the protection actions defined by the user under ANSI, IAC or IEC standards. The operational conditions of the breaker or disconnector are also signalized.

APPLICATIONS
◐  Primary and backup protections for power plants, utility and industrial distribution systems
◐  Protection of transformers, overhead lines, cables and generators
