Training course: Power System Protection


Power system protection systems play a crucial role in establishing reliable electrical power systems. Poorly designed protection systems may result in major power failures. Due to the increasing importance of electricity, such power failures can have a serious impact on society and the economy.

Knowledge of power system protection systems is key when it comes to optimising the reliability level of electrical infrastructures. With the advances in protection and communication technology in recent decades plus the strong increase of renewable energy sources, the design and operation of power system protection systems has become ever more challenging.

This training course presents the fundamentals of power system protection and its application. A very “hands-on” is used to teach the concepts. Understanding is reinforced with real world examples. Interaction is encouraged between participants and the presenters, to underpin the learning objectives.

Your benefits

• Develop an understanding of the most common types of protection.

• Learn how to apply the theory to a range of practical examples.

• Comprehend the jargon when specifying protection and control equipment

• Understand how to determine relay settings, and/or evaluate systems designed by others

For whom?

This course is designed for technical professionals working in transmission or distribution network operator companies, consultancy organisations, in large industries or government organisations involved in design, engineering, commissioning or maintenance of protection systems. It is recommended that participants have at least a Bachelor of Engineering degree.
