Abstract: The transmission line is a vital component of the power system that carries electricity from generating stations to distributions networks. However, these lines are often exposed to various faults such as short circuits, line-to-ground faults, and open circuits caused by environmental conditions or equipment failure. Faults in transmission lines can lead to severe damages, power outages, and safety hazards. To ensure system stability and reliability, a fast and accurate fault detection and protection system is essential. This project aims to design and implement a Transmission line fault safety protection system that can detect faults promptly and isolate the faulty section to prevent further damage. The system utilizes current and voltage sensing techniques, along with relay mechanisms, to identify abnormal conditions and trigger protective actions automatically. The project enhances the reliability and safety of power system by minimizing downtime the protecting electrical equipment. The proposed system is efficient, cost-effective, and suitable for integration into modern smart grid applications.
