ABSTRACT: This study presents a PSCAD simulation model of the 132/11 kV Pencawang Masuk Utama (PMU) in Jasin, Melaka, designed to evaluate the performance of Inverse Definite Minimum Time (IDMT) overcurrent relays. The system was subjected to various fault scenarios, including three-phase bolted, standard three-phase, and double line-to-ground faults across different network locations to assess operating and coordination times. The analysis confirms that the relay response times align with theoretical expectations, verifying the reliability of the protection scheme.
