Mozambique Polytechnic University Relay Protection

PROT 401 provides an overview of the principles and schemes for protecting power lines, transformers, buses, generators, and motors. This training course equips participants with cutting-edge expertise in smart protection architectures, AI-enabled fault detection, advanced relaying schemes, and predictive protection analytics. Protective Relays - Technical Seminar Nov 2016 - Copyright: IEEE 2 Abstract: Protective relays and devices have been developed over 100 years ago to provide "lastline"of defense for the electrical systems. They are intended to quickly identify a fault and isolate it so the balance of the system. In this paper, a new senior-level Electrical Engineering course in power systems is presented.
