The objective of power system protection is to isolate a faulty section of electrical power system from rest of the live system so that the rest portion can function satisfactorily without any severe damage due to fault current. Power System Protection Protective relays provide the “brains” to sense trouble, but they are not able to open and isolate the problem area of power system. endobj A protection relay is a device that responds to abnormal conditions in an electrical power system to operate a circuit-breaker to disconnect the faulty section of the system with the minimum interruption of supply.
