Underground power lines are increasingly being used due to security concerns and greater dependability in circulation systems. These cables are secure and unaffected by severe weather conditions, but they pose challenges in detecting faults and fault locations. The main issue in electrical engineering is determining the fault's location and nature. Repairing faulty cables becomes difficult due to a lack of a proper system for tracking fault locations. Fortunately, advancements in technology and detection schemes are improving fault detection methods in underground cable systems. This scheme focuses on locating faults and identifying phase lines in damaged underground cables. Its tracking system consists of a microcontroller, LCD display, fault-sensing circuit module, and proper power supply arrangement with regulated power output. The current in the circuit is sensed by interconnected relays, and the fault is detected and precisely located.
