3-Day Class (Tues, Wed, Thurs 8:00 am – 4:30 pm), 24 CEUs

Good relay testers need a solid foundation. Graduates from this Protective Relay Testing Fundamentals Class will understand, and be able to test, the most common functions enabled on any feeder relay such as:

  • Time Overcurrent (51)
  • Instantaneous Overcurrent (50)
  • Overvoltage (59) / Undervoltage (27)
  • CO-x or IAC-xx
  • Schweitzer Engineering Laboratories SEL-351
  • General Electric SR-750

You may think that you, or your team, have been testing relays for a while and will get more benefits from the advanced class, but most relay testers who skipped this class wished they would have started here.

Relay testers are often thrown into the fire with little-to-no training. They figure out a test procedure that works for them and share that knowledge with their colleagues and/or the next generation of relay testers. These test procedures may get the passes you need for your test sheets, but most of the test plans we’ve seen during our years of relay training have weaknesses that fail to find the most common problems that occur in modern relays. In fact, we often find problems with relay settings that are in-service and “tested” at our student’s facilities. We encourage you to honestly answer the questions in the “Who should take this class?” section to see if you are ready to skip this class.

Every class we offer is tailored to the students in the room, which means we don’t have a constant stream of PowerPoint presentations and pre-canned exercises! Every class is unique. You are guaranteed to come away from this class with more knowledge and skills to become a better relay tester. You can read some reviews of previous classes by clicking the Reviews tab above.

Who should take this class?

We recommend that all relay technicians take the Protective Relay Testing Fundamentals Class to ensure that they have a solid foundation before attending any of the other classes. We don’t just discuss the mechanics of the topics listed above; we will review all of the fundamentals that every relay tester should know.

If you can’t confidently answer the questions in the quiz below and apply them to your next relay testing project, you should take this class:

    Jason S. CEDA Field Services – Power Systems

    Best relay testing courses out there I know of. The instructor have extensive field experience, thorough understanding of power system theories and years of teaching experience. For someone with power system fundamentals but new to the relay testing field, the “Basic Protective Relay Testing Course” would be a very good starting point. You could learn not only how to conduct a relay test but also the ins and outs behind each step/setting/parameter etc.

    Basic Course Student

    Take the time to utilize this small class setting and ask as many questions as possible.

  3. Rated 5 out of 5

    Anonymous Student

    I would recommend taking the course at your work site in small groups as the one on one instruction was very valuable and the course was able to be tailored to our specific company needs. This also allowed plenty of time for questions and open discussion.

    This is a great class; even if you have little to no experience with relays. Chris can really break things down to the most basic level. Great instruction. Great class.

  6. Rated 5 out of 5

    Mike Adam, Power Ditribution Specialist, Vanderbilt University

    Anyone needing to test relays will benefit from this course. The instructor is very knowledgeable about all relays and test sets. He teaches you how to use the equipment you will use in the real world, and any possible issues that may arise from a particular test set.

    Rowan Dunbar, Independant Consultant for Imperial Oil

    Chris has an incredible amount of knowledge and experience which he shares as he teaches the theory and practical methods of Relay testing. These experiences are so valuable weather you are new or an experienced veteran of relay testing. You get theory and then the opportunity to set up different testing situations to apply and prove the lessons, you can experiment with the circuits and tester until you are proficient. Regardless of the brand of tester, Chris is there to assist and offer advice until you comfortable with the testing circuit and the testers available functions. Excellent opportunity to learn the strengths and weaknesses of different brands of relay test sets. Chris has a natural talent for teaching!

    Daniel Nigra American Electrical Testing

    Chris was an excellent instructor. For an inexperienced tester like myself, he made it easy to follow and understand. I was never bored once in the 3 days. I had never used the doble or the software before, and now I’m confident I have a great base to continue my learning.

    Shaun Robison Test Technician for American Electrical Testing

    Great hands on training with a detailed visual guide. Chris’ experience in the field allows him to bring real world application to the classroom. The hands on training keeps you engaged and helps you understand the theory of operation. I can’t wait to participate in the advanced course in the upcoming weeks.

    Fundamentals Student Review

    If you are having trouble understanding basic fundamentals of relays , this class is taught by an experienced engineer who can succesfully explain what is going on and how to understand it

  18. Rated 5 out of 5

    Rune Winn, Field Engineer, Emerson Network Power

    Chris is extremely knowledgeable and experienced. He has seen almost every mistake that can be made in the protection and control game. This course will provide you with a great step by step guide to testing. Not only will you have a good guide, but you will understand WHY you are doing that step.

    Rob P.

    I would advise future prospective students to at least review the online courses outline but most of all to complete the online courses prior to attending the hands on training as you may think you are further advanced than you really might be. It holds up other students who are more experienced and advanced even if only after following the systematic layout of how the online courses roll into the hands on training.

    A Relay Course Evaluation

    I’ve done enough coursework in my life in various disciplines and trade crafts to have forgotten some of them. In all of my studies, I have rarely met an instructor who knew their material better, delivered it more clearly and effectively, or who obviously enjoyed teaching their subject more. His class helped me understand relay testing at a level far above what I knew before I took it. It would be difficult to overstate the value of his classes.

  25. Rated 5 out of 5


    I was a beginner when I took the Protective Relay Testing Fundamentals Course–very green in the discipline–and I took the class with people who had a range of experience. Some had decades in this specific field while others (like myself) had only a year or so, with several somewhere in between. Because the class is structured as a hands-on test experience of an individual relay element in both its electro-mechanical and digital forms, everyone gets to follow along under instructor guidance. Everyone learned something, and the delivery was as inviting, enjoyable, and enriching as any class I’ve ever taken in any subject or discipline. Relay testing can be an intimidating subject, but this class demystified some of its thornier aspects and Chris taught it in such a way as to make relay testing an inviting and deeply interesting endeavor.
