Power System Protection: Protective Relay Logic Course

Learn about digital logic in protective relays with this online course.

Learn how to implement logic schemes in modern microprocessor-based protective relays.

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 of the multi-part course series, you will learn how to implement digital logic in protective relays. The course is divided into the following sections:

1. Introduction to Protective Relay Logic: we will begin in section 2 of the course by introducing logic gates and how they work. We will also be discussing the order of operation of logic functions and how to develop truth tables to determine proper operation of logic schemes. We will finish the section by discussing some functions commonly used in protective relay logic: timers, latches, and edge triggers.

2. Applications of Logic in Protective Relays: having defined the fundamentals of relay logic, we will move into developing practical examples in section 3 of the course. We will be taking a look at how to build five different logic schemes: enable/disable switches, permissive tripping schemes, overcurrent blocking schemes, breaker failure schemes, and automatic reclosing schemes.

We are confident you will find out that this course is worth the investment, so we offer a 30-day 100% money-back guarantee, no questions asked.

This course is an on-demand video course, which you can watch at your own pace, on your laptop or iOS device using the Kajabi app. It is composed of 13 lectures lasting 2 hours and 15 minutes. Throughout the course, you will learn:

  • How to use logic gates in protective relays
  • How protective relay functions, such as timers, latches, and edge triggers work
  • How to use truth tables to determine protective relay logic operation
  • How to implement different logic schemes, such as enable/disable functions, permissive tripping schemes, breaker failure schemes, and auto reclosing schemes

If at any point you have questions while you go through the course, you can always reach to our course instructor via the built-in comments feature in our platform, or by email at [email protected].

We know it is important to our students to show proof of their continued learning. Because of this, after completing the course, you will receive a certificate of completion.

Note: professional engineers need to complete the course exam and obtain a grade of 70% at a minimum to receive PDHs

What Our Students Say:

I am so impressed with the instructor – I was having difficulty in my project involving Simulink for Power Systems, but when I attended the courses taught by Ricardo and also had a private conversation with him, his response was very fast and accurate. I can say the support I got from Ricardo was excellent. I give Ricardo FIVE STARS!

Ezenwa Udoha

It's well delivered and also quite engaging such that I was able to finish it in one sitting! This course is an excellent refresher for symmetrical components and fault analysis.

The electric power course offerings by Romero Engineering Company are some of the best continuing education courses I've ever had. The courses were very comprehensive and easy to understand, and Mr. Romero provided me high quality instruction. The Simulink tutorials were especially helpful for my master's coursework. Highly recommended!
