Course Details

This is a practical course in power distribution, focusing on medium voltage (1kV- 36kV) power considerations, switchgear, power cables, transformers, power factor correction, earthing, lightning protection, and network studies.

This course will help you understand practical power distribution fundamentals, determine short-circuit ratings quickly and effectively, and assess the influence of fault levers on switchgear ratings.

We will cover how to select the correct type of switchgear for the right application, and evaluate the advantages of modern state-of-the-art switchgear protection for your applications, including preventative maintenance information. You will also learn how to identify the different applications for various cable insulation types and how to specify correct power cable installation methods.

This course will also help you understand when and how to use single core cables versus three-core cables, as well as how to use and protect power transformers correctly. We will cover the ways of assessing and specifying correct grounding/earthing throughout your electrical network, and how to determine the need for Power Factor Correction (PFC) for your environment.

On top of this, you will learn how to assess the economic justification for installing PFC equipment, correctly specify PFC equipment and be aware of practical consequences, and confidently use computer simulation software to solve and predict power network problems.

The course is composed of 12 modules, covering topics such as correctly implementing the right type of switchgear for the appropriate application, economically selecting and installing the best-suited power cable for a specific use, implementing successful maintenance strategies and procedures, and effectively using software techniques to solve problem areas in your power network.
