Course Description

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 power transformers.

We will begin the course by giving a brief review of how power transformers are connected and how they operate, so that we can understand why and how to protect them from faults and abnormal operating conditions. We will then move on to discuss in great detail all the different protective elements that are used in industry to protect transformers. These include: phase differential (87P), ground differential (87G), instantaneous and inverse-time overcurrent (50/51), neutral inverse-time overcurrent (51N), and volts/hertz (24). We will end the course by explaining how an SEL-487E protective relay can be used for the protection of a power transformer.

By understanding how power transformers 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 we are also always available for questions while you go through the course to ensure everything is clear.

See you in the course!
