Objective of power system protection 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 severer damage due to fault current.
Problems on the power system include.
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.
Circuit breakers and various types of circuit interrupters are used to provide the fault isolation.
The objectives of power system protection are to.
Most have overload protection but often malfunction causing fire.
