  • Relay protection frequency too high

    Relay protection frequency too high

    Over frequency protection is configured by applying a set point above normal operating frequency. If the frequency of an installation exceeds its acceptable limits, the information delivered by the under/overfrequency protection can be used to initiate appropriate action to restore good. Protective Relays - Technical Seminar Nov 2016 - Copyright: IEEE 2 Abstract: Protective relays and devices have been developed over 100 years ago to provide “lastline”of defense for the electrical systems. They are intended to quickly identify a fault and isolate it so the balance of the system. Frequency protection monitors the power system frequency, and signals when the frequency departs from normal. For example, unselective protection operation during a medium voltage network fault will cause an outage for an unnecessarily large number of consumers. By continuously monitoring the rate of frequency change (frequency slip), it identifies severe power imbalances or faults in the.
