The complexity and size of the electrical power system have resulted in economic consequences and reduced reliability caused by power system faults, with traditional power grids being susceptible to faults and making it difficult to promptly detect and repair them; however, the innovative solution of Smart Grid technology in self-healing electrical power distribution systems offers a more reliable and sustainable power supply for the future by enabling automatic fault detection and recovery, thereby minimizing the impact on the power supply. The main aim of this study is to develop a system that detects and protects against faults while also exploring fault location and isolation, as well as communicating with the power supply center during fault occurrences and sending messages to the firefighting center in the event of a fire. As a result of this research, we have developed a prototype capable of detecting, protecting, and isolating faults in power distribution, including single line-to-ground faults, line-to-line faults, and triple line faults, while also having the ability to communicate with the power supply center during fault occurrences and send messages to the firefighting center in the event of a fire.
