Disturbances in 20 kV medium-voltage distribution networks have a significant impact on increasing power losses and reducing system reliability. This study aims to identify and analyze the causes of power losses resulting from distribution network disturbances by applying Fault Tree Analysis (FTA) and Failure Mode and Effect Analysis (FMEA), supported by simulations using ETAP software. The FTA method is employed to determine the root causes of disturbances through cause–effect relationships within the distribution system, while FMEA is used to evaluate the risk level of each failure mode by calculating the Risk Priority Number (RPN). Furthermore, ETAP simulations are conducted to assess active and reactive power losses as well as voltage profiles before and after technical improvements are implemented. The analysis results indicate that power losses are caused by several factors, including insulator damage, conductor or power cable failures, cable joint defects, distribution transformer issues, environmental disturbances, and protection equipment failures such as fuses and reclosers. Based on the RPN values, components with the highest risk levels are prioritized for corrective actions. ETAP simulation results demonstrate that transformer tap adjustment, conductor cross-section replacement, and capacitor bank installation effectively reduce power losses and improve voltage quality. This study is expected to serve as a reference for enhancing the efficiency and reliability of power distribution systems.
