ABSTRACT Conductor failure or outage in general does not promote development to public and private sectors. Development of our country and in addition, there are processes that need not to be interrupted because of their importance. This project presents the design, construction and implementation of a broken ac conductor for automatic detection of a broken ac conductor. Studies have shown that the electric fault which occurs in this facilities constitute the major cause of service interruptions as a result of their exposure to high currents, mechanical strains, utilization by the high currents consuming appliances used for a long time thus it’s difficult to locate the accurate location of the broken conductor. and because now days’ electric cables are being installed inside the walls using the pvc conduits or are being installed underground by the use of underground cables and because of this people generally replace the broken conductors instead of repairing them due to hardship in locating the exact place where the cable is broken therefore the reason of coming up with this project was to facilitate quick locating and isolation.
