Course Outline
After participating in this course, you will be able to:

€¢ Apply your knowledge of the fundamentals of the utility power supply system and power quality and how it impacts on
   the industrial/commercial user
€¢ Recognize the most important operating characteristics of the major power components
€¢ Discriminate between the criteria governing the application of overcurrent and overvoltage protective devices
€¢ Implement better start-up and regular maintenance of electrical installations
€¢ Consider electricity rates with the knowledge of the factors that impact on them
€¢ Improve your substation grounding
€¢ Benefit from the experience of your instructor and other participants who have encountered and solved similar situations


Substations play an important role in a power system network in maintaining the continuity of power supply and power quality to the industrial and commercial consumers. The high voltage substation comprises of switching equipment, transformers, reactors, var compensators, protection, control, automation and communication. A properly planned and designed substation is essential for the reliable operation of power system network.

This course covers all aspects of high and medium voltage substation design including regulatory and environmental requirements, general design considerations, application of switching and power equipment, fault calculations, safe grounding design, protection/control, automation and communication, and maintenance considerations.


To provide a practical understanding of planning, design, application and maintenance aspects of high and medium voltage substations for utility networks and industrial plants.

Who Should Attend

Electrical power generation systems and distribution engineers in utilities and industrial plants, managers of private electricity producers and large power consumers, substation engineers, consulting engineers, manufacturers of power equipment, technicians and technologists and other technical personnel involved in the design, operation and maintenance of high/medium voltage substations.

The course was very well presented and the course instructor was absolutely amazing.
Reviewed by 2013
Our instructor, Stephen Lamming, was outstanding and a true expert in his field. He was able to complement the technical air monitoring information with practical real life examples which was highly beneficial. He is an excellent communicator and was highly interactive with the course attendees. This course was recommended to me because Stephen Lamming does an outstanding job. I was very impressed with this course and have subsequently recommended it to my colleagues.
