DESIGNS DEVELOPMENT AND TESTING OF STATIC PROTECTIVE RELAY FOR POWER SYSTEM

Abstract

Although there has been active int•res't in static relays for more than . 3') years, it is only with. the advent of mode semiconductors that priable progress has been made. The increas. ing performance required of modern protection is reaching the limits of capability of electronocha. noel relays# and practical development of static protection with higher p+erformanc. and greater potentiality is becoming increasingly necessary, This dissertation is an attempt to develop a proto type static single phase distance relay, Mho type with direct phase coparison technique. The development with basic construction of static relays have been reviewed . The relmh static and dynamic performance have been described.
