Street lighting systems are a critical component of urban infrastructure, present in nearly all public areas. Faults occurring at lighting poles can pose serious safety hazards to both people and animals. Experience from the field shows that existing protection systems often fail to operate reliably in certain areas, highlighting the need for more effective fault management solutions. In this study, we propose a method for detecting and localizing faults in low-voltage lighting systems by analyzing voltage drops caused by fault currents. The approach uses terminal voltage measurements and does not require complex communication or synchronization. Simulation results based on a real-world lighting system model demonstrate the high accuracy of the proposed method, with fault localization errors remaining below 2%. It also demonstrates strong robustness against variations in fault resistance, maintaining high localization accuracy.
