چکیده
This paper presents the development of a novel digital relay automated evaluation program and its important aspects. The goal of relay’s test automation concept is to use the relay expert's time as efficiently as possible. It shall be the tool to increase the depth of testing while decreasing the testing time, allowing the expert to use his valuable time to eliminate possible errors in the protection system. It is the ideal method to visualize, document and handle the complexity of powerful modern protection relays.
