Electrical faults such as overvoltage, overcurrent, and over-temperature can lead to serious damage to equipment and pose a safety risk to personnel. To address these issues, the Internet of Things (IoT)-based fault detection system has been proposed. The system utilizes IEEE standards for communication and data transfer and includes sensors for detecting over voltage, over current, and overtemperature, as well as a breaker trip detection mechanism and relay for isolating faulty equipment. The system is designed to continuously monitor the electrical parameters of equipment and provide real-time notifications of any faults detected. It also incorporates a fault management module that can prioritize and alert personnel of critical faults. The proposed IoT-based fault detection system provides a reliable and efficient solution for detecting and managing electrical faults in the industrial sector. It has the potential to reduce equipment damage, increase safety, and improve operational efficiency.
