With the rapid development of smart grids, the safety of power distribution systems has become a critical concern in electrical engineering. Fault arcs, due to their hidden nature and destructive potential, often cause line overheating, equipment damage, and even fires, posing serious threats to the stable operation of power systems. This study focuses on fault arc detection technology and establishes an electrical safety evaluation model for smart distribution systems. By analyzing the coupling relationship between arc characteristic signals and system operating conditions, we propose a comprehensive evaluation method based on intelligent algorithms to achieve dynamic monitoring and early warning of potential risks. The research results demonstrate that this approach can effectively enhance the safety level of distribution systems, providing theoretical support and technical foundations for the reliable operation of smart grids.
