The project can detect any fault in underground cable from base station in km. It takes a lot of time in finding the exact location of the fault. Hence by using the concept of Ohms law, it becomes easy to find the exact location. According to the law, when a low DC voltage is applied on the feeder end by a series resistor, then the current will differ on the basis of the location of fault. If there happens to be short circuit then the voltage across the series resistors i.e. cable lines changes respectively. This voltage change is then fed to an ADC that produces digital data and is displayed in km by the microcontroller. The project uses a set of resistors for cable length and a set of switches for creating faults. The microcontroller thus displays the distance and respective phase on a LCD screen where the fault has occurred.
