Introduction

The Electrical Operation and Protection (Theoretical Approach) training program is designed by Global Horizon Training Center to provide participants with a comprehensive understanding of the fundamental principles, concepts, and practices related to electrical system operation and protection.

The program focuses on the theoretical aspects of electrical power systems, including electrical system components, operating principles, protection systems, fault conditions, protective devices, circuit breakers, relays, transformers, motors, and electrical safety. Participants will develop a solid understanding of how electrical systems operate and how protection schemes are designed to detect and isolate electrical faults.
