摘要： The invention specifically relates to a protection relay that generates a trip signal to operate a circuit breaker in case of fault condition. The protection relay comprises of a first module (505) for measurement and analysis of power parameters of the power line connecting the power equipment that is being protected, the protection being provided by generating a first trip signal (540) for operating a circuit breaker connected in the power line. The protection relay also comprises of one or more second modules for boosting performance of the protection relay. There is second module that performs measurement and analysis of power parameters (503) to generate a second trip signal (530) for operating the circuit breaker connected in the power line. The first trip signal (540) and the second trip signal (530) from the protection relay are logically combined (550) to generate a trip signal (560) that operates the circuit breaker.
