Symmetrical Components Based Method for Distribution System Overcurrent Protection

Mrs. Kawita D. Thakur, Dr. V. N. Gohokar

Control and reduction of the fault currents in power distribution systems feeding large number of electrified consumers are a significant issue as it can damage all other electrical equipments and threatens supply continuity. The power system maintains its steady state mainly because of the correct and quick remedial action taken by the protective relaying equipment. Often with the settings of protective relaying systems, the relay responds to non fault or switching transients too. The response of the protection system must be automatic, quick, and should cause a minimum amount of disruption to the power system and must have to be inoperative to switching conditions. This paper will explore the method of symmetrical components for discrimination between faults and switching events in distribution system overcurrent protection
