Recently, advanced digital protection relays were developed in Japan. This improved relaying system for the next generation is expected to have higher performance for the discrimination of the fault, functions for multi-purpose use of acquired data, easy operation and maintance, and also have friendly man-machine interface. This paper describes the system configuration of the developed relay and its representive characteristics.
