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 prot...

The paper is focused on the protection of 132Kv line using microprocessor based control approach. A detailed review of the literature reveals that this technique is more efficient and has many advantages over other techniques developed for this purpose. Microprocessor based protections are more reliable, flexible and faster than conventional protection schemes. The protection schemes proposed a...
