A novel technique for the fault detection & protection of 11kv distribution lines is proposed, to improve distribution reliability via detection of distribution faults and determination of their location. The proposed system uses different protective equipment’s, Fault passage indicator (FPI), Data Communication Unit (DCU), SCADA (System control & Data Acquisition) and GPRS/HSPA module. The latest fault detection system involves an integration of FPI, DCU, and SCADA systems to provide distribution dispatchers with a graphical display of possible locations for faults. The faults like all series & shunt faults get detected according to characteristics condition of current & voltage at the occurrence of fault in the three phase overhead lines. The sensed signals are given to Data Communication Unit for detection of faults. Also, wireless mobile communication technique i.e. GPRS is used simultaneously to notify to responsible person operating SCADA system. Simultaneously system gets isolated using protective devices (Air break switch).
