About the course

This course applies fundamental electrical equipment principles. The course is designed to facilities Engineers and Technicians with or without a background in electrical engineering and can accelerate the development of new facilities Electrical Engineers. Through the use of individual and group problem solving, attendees will learn about transformers, motors, generators, cables, protection of power system and circuit breakers, emergency power, site and standby generation and electrical safety. Participants will gain a better understanding of electrical components and systems and will develop a greater appreciation for electrical engineering and Technicians.

Course Objectives

On completion of this course participants will be able to know:

  • The key components of facilities electric power distribution which include circuit arrangements, low and medium voltage switchgear, and single-phase and three phase schemes
  • Operation, components, electromotive forces, turns and voltage ratios, losses, efficiency, rating, and connections of transformers
  • The difference between direct current motors, alternating current motors, enclosures and how to select motors
  • Protection of electrical equipment including fuses, direct tripping, relaying, and coordination
  • About emergency power to include power requirements, generator sets, direct current systems, batteries, and an overview of uninterruptible power supplies (UPS)
  • Power generation which includes an overview of emergency, prime, base, peak and co-generation, quality, sizing, operation, control, and power factor correction
  • Grounding and bonding with an overview of systems, equipment, ignition sources, separately derived systems, performance, and substation grounding
