Most of the worldwide run on the low voltage and medium voltage distribution lines underground cables from many decades cables were used. To deduce the sensitivity of distribution networks which cause environment influences high voltage underground cables are used more and more. This paper suggests model for underground power cable fault position using microcontroller. The purpose of this project is to determine the distance in kilometers between underground cable fault and base station. This project uses the simple notion of the law of ohm. If any short circuit-like fault occurs, the voltage drop can vary depending on the length of the cable fault, because the current varies. Therefore, a series of resistors are used to reflect the cable and a dc voltage is fed at one end, and the fault is identified by detecting the voltage shift using an analog to voltage converter and a microcontroller is used to make the calculations required to show the fault distance on the LCD monitor.
