This paper is intended to detect the location of fault in underground cable lines from the sub station to exact location using an Arduino board. In the town areas, the electrical cable runs in undergrounds instead of overhead lines. Whenever the fault occurs in underground cable it is difficult to identify the exact location of the fault for process of repairing that particular cable. The proposed system finds the actual location of the fault. This system uses an Arduino microcontroller board and a rectified power supply. Here the current sensing circuits made with a combination of resistors are interfaced to Arduino micro controller board to help of the internal ADC device for providing digital data to the microcontroller representing the cable length in kilometers. The fault creation is made by the set of switches. The relays are controlled by the relay driver. A 16x2 LCD display connected to the microcontroller to display the information. In case of short circuit the voltage across series resistors changes accordingly, which is then fed to an ADC to develop precise digital data to a programmed Arduino micro controller board that further displays exact fault location from base station in kilometers. Whenever a fault occurs in a cable the buzzer produce the alarm to alert and to take an immediate action by field workers.
