Power cables that are used to a supply electrical power is placed underground to avoid unwanted interference. This makes it very tough to determine the exact location of the faults that occur. A fault might occur due to a many of reasons such as digging, earthquake, construction work, etc. The maintenance process related to that particular line is difficult due to unknown location of the fault in the line. In this paper, we want to present the working of a self-made hardware model illustrating the detection of faults in underground power lines using Ohm’s law. The voltage drop is measured across regular intervals of the line. As soon as the fault occurs, the voltage drop across each interval varies in accordance with the Ohm’s law. AT Mega 16 micro controller has been used in the hardware model. The project detects the location of fault in underground cable lines from the base station to exact location in kilo meters use the micro controller kit. In metropolitan areas, the electrical cable runs in undergrounds instead of overhead lines. Whenever the fault occurs in underground cable it is tough to detect the exact location of the fault for process of repairing that particular cable. The underground fault detection system finds the exact location of the fault
