The Underground Cable Fault Detection System is intended to detect the location of fault in underground cable lines from the base station in km using Arduino. To locate a fault in the cable, the cable must be tested for faults. The prototype uses the simple concept of Ohms law. The current would vary depending upon the length of fault of the cable. In the urban areas, the electrical cables run in underground instead of overhead lines. Whenever the fault occurs in underground cable it is difficult to detect the exact location of the fault for process of repairing that particular cable. The proposed system locates the source of the problem. The prototype is built with a set of resistors representing cable length in kilometers, and faults are created by a set of switches at each known distance to ensure accuracy. In the event of a fault, the voltage across series resistors changes accordingly, which is then fed to an ADC to generate precise digital data, which is then displayed in distance by a programmed Arduino. A 16X2 LCD interfaced with the microcontroller displays the fault occurrence distance, phase, and time.
