Power System Protection: Busbar Protection from Udemy

This course is part of a multi-part course series about one of the main areas of power engineering: power system protection and control. Power system protection and control ensures the reliable continuous operation of power systems and is therefore an essential area of power engineering. In this course, you will learn about the different protective elements used for the protection of substation buses.

We will begin the course by giving a brief review of the different types of substation bus arrangements typically found in power systems, so that we can understand why and how to protect them from faults and abnormal operating conditions. We will then discuss, in a great amount of detail, all the protective elements used in industry for the protection of substation buses. These include: current differential (87) and high-impedance voltage differential (87V). We will end the course by explaining how an SEL-487B protective relay can be used for the protection of a substation bus.

By understanding how substation buses operate and how to implement different protective elements for their protection, you will be able to design robust protection schemes to protect these components from faults and abnormal operating conditions.

Remember that Udemy offers a 30-day money-back guarantee. I am also always available for questions while you go through the course to ensure everything is clear.
