Protective Relay Definition: A protective relay is an automatic device that senses abnormal conditions in electrical circuits and triggers actions to isolate faults. Eng, IEEE Life Fellow IEEE/IAS/I&CPSD Protection & Coordination WG Chair Jacobs Canada, Calgary, AB rasheek. Open circuit faults are less frequent than short circuit faults, and often they are transformed in to short circuits by subsequent events Switchgear and protection are essential components of electrical power systems, ensuring.
