Abstract : This paper proposes fault location model for underground power cable using microcontroller. The aim of this project is to determine the di stance of underground cable fault from base station in kilometers. This project uses the simple c oncept of ohmís law.When any fault like short circuit occurs,voltage drop will vary depending on the length of fault in cable,since the current varies. A set of resistors are ther efore used to represen t the cable and a dc vol tage is fed at one end and the fault is detected by detecting the change in voltage using a analog to voltage converter and a microcontroller is used to make the necessary calculations so that the fault distance is displayed on the LCD display.
