Electrical Power System Fundamentals for Non-Electrical Engineers

THE WORKSHOP

The focus is 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 workshop.

The workshop will commence 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 first day will be concluded with coverage of power system components in terms of isolators, fuses and circuit breakers.

The second day will commence with an examination of AC and DC motors, followed by a review of electrical lighting and illumination concepts. The power hungry topic of electrical heating 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 workshop is concluded with modern developments such as substation automation, the smart grid, industrial data communications and the still controversial topic of carbon trading.

A workshop such as this is certainly not going to make you a professional electrical engineer - although many experienced electrical engineers have commented on how useful this course has been in broadening their perspective in other areas of the electrical world. But in two action packed and enjoyable days, you will leave with a valuable toolbox of skills in electrical engineering, thus becoming far more productive and safer in your career and in working with electrical engineers, technicians and managers.
