Abstract: The reliability of electrical power systems is crucial for industrial and domestic applications, yet they are highly vulnerable to faults such as short circuits, overloads, and transformer malfunctions. Identifying faults quickly and accurately reduces downtime, prevents accidents, and improves maintenance efficiency. This project proposes an IoT-based system using Arduino to monitor transmission lines and transformers, detect faults, and estimate the distance of the fault location. The system collects real-time data from sensors, processes it through Arduino, and transmits the fault status to an IoT platform, enabling remote monitoring and timely corrective action.

Keywords: Electrical Power Systems, Arduino Uno, Transformer Malfunctions, Iot Platform, Remote Monitoring.
