Fault Detection and Response at Pencawang Pembahagian Utama, Banting Selangor: A focus on Overcurrent Protection Relay using PSCAD Software

Abstract

Overcurrent faults are prevalent issues in electrical distribution systems, characterized by electrical disturbances where the electric current exceeds the safe limit within a connection. 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 paper assesses the effectiveness of fault detection and tripping response of an overcurrent relay at the main distribution panel in Banting, Selangor, using PSCAD software as the research platform. This study analyses the overcurrent relay setting and tripping response, in detecting excessive current events, focusing on the different network configuration. Through data observation and analysis, the research verifies the effectiveness of the overcurrent fast relay response in the main distribution panel in the event of large fault current. The findings provide valuable guidance for the relay behavioral and proper enhancement of relay reevaluation which aims to improve the safety and stability of the electrical supply for end-users.
