An effective high impedance fault detection and location in a power transmission line is implemented using zigbee. When HIF is detected in the power transmission line the presence of the fault in the particular location in the transmission line made to transmit to the nearest substation. There by the power through that transmission line is shutdown and is made retransmit through the secondary transmission line. In doing this the accidents can be avoided caused due to the High Impedance Faults and efficient power transmission can be provided to the end users. The High Impedance Faults in the transmission line are detected and located by using the current sensor and the PIC microcontroller placed at each power transmission line pillar. The location of the High Impedance Faults is transmitted to the nearest substation by using zigbee through various transmission line pillars. By this the High Impedance Faults can be easily located and also can be corrected in very quick time. So this technique helps us to provide the efficient power transmission and distribution system to the society and accidents occurring due to High Impedance Faults can be avoided to the maximum extent.
