Fault level analysis of power distribution system

Fault level analysis in power distribution system is important issue in power system protection study. Demand of power increases day to day. So, continuous power supply to the consumer is necessary without any interruption. Fault analysis in power distribution system is necessary for selection of proper protective devices such as relays and circuit breakers. So that fault is cleared as early as possible and equipments in the substation are protected from heavy short circuit current. In this paper, fault level analysis of 33/11 KV power distribution substation is studied.
