Electrical Power System Fundamentals for Non-Electrical Engineers - 4 hour online course

THE COURSE

This course will focus on the building blocks of electrical engineering, the fundamentals of electrical design and integrating electrical engineering know-how into the other disciplines within an organisation. Unnecessary theory will be minimised and you will focus on best practice over the duration of the course.

The course will begin by reviewing basic electrical circuits and electrical laws. You will then be exposed to the basic principles of electrical generation, transmission and distribution. Electrical distribution will then be covered in considerably more detail.

The interesting area of electrical measurements, as applied to single phase and three phase systems, will then be reviewed. You will be exposed to earthing with a strong focus on safety issues. Transformers will then be examined with an emphasis on power transformers as used in the electrical distribution industry. The session will be concluded with coverage of power system components in terms of isolators, fuses and circuit breakers.

The next session will commence with an examination of AC and DC motors. The power hungry topic of electrical heating and cooling in industry is then examined. The impact, especially in the modern world of power electronics, is discussed with a demonstration of the possible unpleasant harmonics arising from using this powerful technology. This then smoothly leads into the topic of dealing with power quality. The last three major topics are electrical power system protection, electrical safety and customer installations. The penultimate topic of great interest to executive management in a company (and indeed municipalities and governments) is load forecasting.

The course is concluded with modern developments such as substation automation, the smart grid, industrial data communications and the still controversial topic of carbon trading.
