Abstract	Underground power cables are increasingly preferred in modern distribution systems due to their improved safety, reduced exposure to environmental conditions, and better suitability for urban infrastructure. Despite these advantages, identifying faults such as cable breakage remains a difficult task because the lines are not directly visible. Conventional fault detection methods are often time-consuming and rely heavily on manual inspection, which delays maintenance and affects supply continuity. The proposed system presents an automated approach for detecting cable faults in underground three-phase distribution lines. It incorporates switching units, an Arduino-based control system, and a NodeMCU module for communication. Each phase line is continuously monitored, and any abnormal variation in electrical conditions is captured through the switching mechanism and processed by the controller. Once a fault is identified, the system determines the affected phase and displays the information locally while also initiating protective actions through relay.
