Under-voltage and overvoltage protection relay
VMPR Orion Italia

  • under-voltage and overvoltage protection relay VMPR Orion Italia
The Voltage Measurement and Protection Relay (VMPR) has been designed to measure the line or phase RMS voltages under normal conditions or under disturbances. This information is internally processed by the microprocessor, to take the voltage protection actions defined under ANSI or IEC standards. Additionally the operational conditions of the breaker or disconnector are also signalized. The different functions provided by the VMPR may be classified into the following groups:

Applications:
- Protection of generators, motors and transformers against adverse system voltage conditions.
- Supervision of automatic transfer switching schemes.
