General Overview
The Protection of Electrical Systems course is a specialized training program designed to deepen the theoretical understanding of protection systems within electrical circuits and networks. It focuses on the engineering and functional principles used to detect and isolate faults. This course provides comprehensive knowledge regarding protection system components, such as Relays and Circuit Breakers, and covers common fault types including short circuits, overcurrent, and unbalanced phases. Delivered as a purely theoretical framework, it does not include practical exercises or field applications.
The curriculum covers essential aspects such as protection coordination, the classification of systems by function (Current, Voltage, and Frequency protection), and their role in ensuring operational continuity and the safety of both equipment and personnel. The content is presented in a systematic and clear manner, enabling trainees to understand how to design effective protection schemes, analyze system behavior during emergencies, and make decisions based on precise technical insights. This course is ideal for electrical engineers, operations supervisors, and network planners in the power, industrial, and infrastructure sectors.
General Objective
The Protection of Electrical Systems program aims to provide trainees with an advanced theoretical understanding of the engineering and operational framework of electrical circuit protection. The focus is on ensuring operational safety, protecting assets, and improving network stability. The program seeks to consolidate knowledge of the foundations of protection systems, such as the principles of detecting current or voltage deviations, isolation speed, and the accuracy of “selectivity” between actual faults and normal operating conditions.
The general objective focuses on developing the trainees’ ability to understand how protection elements integrate within a network, the role of each component in preventing fault escalation, and maintaining power supply continuity. Furthermore, it introduces participants to analyzing protection system performance, understanding coordination requirements between different relays, and the role of international standards (such as IEEE and IEC) in guiding design. This program is a pivotal step toward building comprehensive technical awareness of protection in electrical systems.
