        abstract = {This paper presents a smart and cost-effective solution for detecting faults in underground transmission lines using an integrated Arduino and MATLAB-based distance relay system. Underground cables are increasingly replacing overhead lines in urban networks due to safety and aesthetics, but locating faults in these cables remains challenging. The proposed system uses Ohm’s law principles to estimate fault distances by measuring voltage drops and resistance changes during fault conditions. The Arduino microcontroller processes real-time analog data, while MATLAB is employed for simulation, visualization, and validation. This hybrid approach facilitates accurate fault location, reduces maintenance delays, and improves the reliability of power distribution systems.},
