Objectives of Relay Protection Operation

Home / Objectives of Relay Protection Operation

Protective relays are essential devices used in electrical power systems to detect faults and abnormal conditions, initiating corrective actions to prevent equipment damage and ensure system stability. Selectivity is a mandatory requirement for all protection, but the importance of it depends on the application. For example, unselective protection operation during a medium voltage network fault will cause an outage for an unnecessarily large number of consumers.
