Schweitzer 0700G11A1A1A77850000 SEL-700G Generator Protection Relay Unit

Feature & Principle

This IED acquires CT and PT signals, executes overcurrent, differential, reverse power, loss of excitation, over/under voltage and frequency protection functions. It sends trip signals to breakers when generator faults occur, records fault waveforms, supports local HMI and remote SCADA communication.
