This paper presents the design and implementation of an intelligent system for transmission line cut-off fault detection and
indication using Internet of Things (IoT) technology. Reliable power supply is a critical requirement in modern electrical infrastructure;
however, transmission lines are frequently affected by faults such as overvoltage, overcurrent, and line interruptions, leading to
power outages and equipment damage. Conventional fault detection methods rely heavily on manual inspection, resulting in
delayed response and reduced system efficiency.To address these limitations, the proposed system utilizes an ESP32 microcontroller integrated with voltage and current sensors to continuously monitor electrical parameters in real time. Upon detecting abnormal conditions, the system promptly identifies faults and activates a relay mechanism to isolate the affected section, thereby enhancing system safety. Additionally, the integration of GSM communication enables instant fault notifications to the electricity board,
while IoT connectivity facilitates real-time monitoring and data visualization through a mobile application. A local LCD display is also
incorporated for on-site status indication.
