Abstract

A protection relay is disclosed that generates a trip signal to operate a circuit breaker in case of a fault condition. A first module provides 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 for operating a circuit breaker connected in the power line. One or more second modules can boost performance of the protection relay by measurement and analysis of power parameters-to generate a second trip signal for operating a circuit breaker connected in the power line. The first trip signal and the second trip signal are logically combined to generate a trip signal that operates the circuit breaker.
