Frequency Relay FR 95

          The Frequency Relay is designed to monitor the system frequency. When the frequency moves outside the setpoint limit the relay will operate giving an alarm or tripping signal. Since speed is propotional to frequency , it can be used to protect A.C. generator plant against overspeed or underspeed.
