UNDERGROUND CABLE FAULT DISTANCE LOCATOR BY USING MICROCONTROLLER

This paper conclude that the underground cable fault location model by using microcontroller. The purpose of project is to identify the cable fault distance from initial position in terms of kilometer. By using simple method of ohm’s law. when any fault occur like short circuit or open circuit hence the voltage loss is increases with the length of fault into the cable, due to this current is varies. Cable is represented by using set of resister. And DC voltage is applied at one side of wire and fault is find due to change in voltage. For the calculation of the distance microcontroller is mainly used. So fault distance is show on the liquid crystal display [LCD].
