Fault in a power system is cleared by a protection scheme which comprises of different components such as relay, circuit breaker and accessories. Collective action of all elements in a protection scheme is necessary to correctly identify and isolate a fault selectively. Failure of any element in such a protection arrangement may lead to unwanted line trip risking further outages in the network. This work proposes a wide area measurement system (WAMS) data-based technique for online identification of failure of protection element for a transmission line. Synchronised voltage–current phasors along with relay decision and circuit breaker status signals are used to calculate indices which identify the failed component. The proposed method is tested for 39-bus New-England system and found to be accurate.
