ABSTRACT: Overcurrent faults are the critical issues in electrical distribution systems, characterized by high electrical current disturbances that exceed the safe limit for the electrical apparatus. These faults can be caused by equipment malfunctions, short circuits, or imperfections in protective devices, posing risks such as equipment damage, fires, and disruptions in the electricity supply. This research assesses the effectiveness of protective systems in the main distribution panel in Banting, Selangor, using PSCAD software as the research platform. The main distribution panel is critical for ensuring safe and reliable electrical power to end-users, and any faults within it can lead to widespread power supply issues. This study evaluates the overcurrent relay, a crucial component in detecting excessive current events, focusing on its configuration, programming, and operation. Through data collection and analysis, the research verifies the effectiveness of the protective system within the main distribution panel. The findings provide valuable guidance for the maintenance and enhancement of protective systems, aiming to improve the safety and stability of the electrical supply for end-users.
