The aim of this course is on the building blocks of electrical engineering, the fundamentals of electrical design and integrating electrical engineering into the other disciplines within an organization. The course will start by reviewing basic electrical circuits and electrical laws. The candidates will be exposed to the basic principles of electrical generation, transmission and distribution. The interesting area of electrical measurements as applied to single phase and three phase systems will then be reviewed. The candidates 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. Topics such as power system components in terms of isolators, fuses and circuit breakers will also be covered.

By the end of this course delegates will learn about:

• The basics of electrical power engineering
• Basic electrical design rules
• Practical steps in selection, installation and commissioning of electrical systems
• How to work more effectively with electrical engineering professionals
• How to apply the local electrical codes effectively
• The role that electrical power plays within your organization

Electrical contractors, new electrical engineers and technicians, non-electrical engineers and technicians, non-electrical personnel who want to understand the broader picture, plant and facility engineers, administration staff, civil, mechanical, chemical, mining engineers, technologists and technicians
