Description

  • Have you ever wondered how generators create electricity in a three-phase power system?
  • If your test set reports time delays in seconds, but the relay is supposed to operate in 6 cycles, how would you figure out if the test passed?
  • Have you ever noticed that your SEL relay frequency tests are always a little off? And the further the test frequency gets from 60 Hz, the worse it gets?
  • Can you tell the difference between an ABC or ACB in a three-phase power system by looking at the waveforms?

We have your answers in this online training course.

Relay testers are often thrown to the wolves and expected to just “figure it out.” Unfortunately, this often means that you figure out what you need to do to get that pass on your test sheet, not realizing why your tweak to the test plan worked. This usually works for a while until it doesn’t, and you’re back to square one. It would be an easy fix if you would have received the proper training from day one.

We will cover the following topics in this lesson to give you a foundation in three-phase electrical theory to help you become a relay testing craftsman that will help you quickly and easily troubleshoot some basic problems with test-plans that leave others frustrated:

  1. Eric (verified owner)

    I found this course to be very useful in understanding the fundamentals of three phase power systems. It was extremely easy to follow along. Very clear, cadenced rhythm with the video narration allowed me to understand without having to backtrack.

    The course material would be suitable for technicians or students looking to get a grasp on three-phase power systems and converting between cycles and seconds; a must have for any relay technician.

    I appreciated the real world examples and exercises, which will help me when I come across these specifics problems in the microprocessor based world of protection relays.

    Overall I highly recommend this course!

  2. joe (verified owner)

    I learned a lot from this course. Having no relay testing experience, I was grateful the real world examples were shown. I will definitely continue with this program, as they become available

  3. Online Student

    very informative

  4. Ahmad Shabazz

    Great fundamental courses, preparing you for any relay testing out there.

  5. Post-Course Evaluation Form Comments

    Excellent refreshers for someone in the field who doesn’t deal with phasers and/or frequency/time/cycles conversions very often.

  6. Customer Review Form

    Great for satisfying NETA training requirements.

  7. Customer Review

    Why should someone take this course?

    “To prepare you for a career in relaying protection.”

  8. Customer Review

    If you want to improve your overall knowledge of three phase power systems you should take this course

  9. Online Student

    Very good course to take online!

  11. Customer Review

    If you are in relay P&C, you need this course for success in your field

  12. Brandon H.

    The course was easy to follow along, very interactive, and descriptive.

  13. Rob P.

    In order to clarify already understood concepts and learn new ones in order to make themselves a more confident and reliable relay tester and commissioning tech. Also to be able to mentor in the correct manner to hopefully eliminate some of the so many bad habits of testers in the industry.

  14. A Relay Course Evaluation

    If you want to take your relay testing knowledge to the next level, this course is a must!

  15. A Relay Course Evaluation

    Excellent

  16. Relay Course Evaluation

    If you don’t have any experience about relay testing, this will be little bit hard to understand. However, in my case, I just watched this course so many times before relay testing and now, I can go on right way to do it with confidence. This is really valuable for your carrier as relay tester.

  17. Relay Course Evaluation

    How did you feel about testing relays before the course?
    I have never experienced before and just did bench top relay testing.
    How did the course help you?
    increase my knowledge regarding protection relay world and now I did my first job of SEL-700G for FAT testing.
    How do you feel about relay testing now?
    Very exciting and there are lots of fun and interests.
    Why should someone take this course?
    to verify their knowledge with other expert. since sometimes, they are very stubborn and tend to believe their experience.

  18. A Relay Course Evaluation

    Everyone who works on power systems in any capacity needs a thorough understanding of phase sequence/rotation because its not a matter of if you’ll need it, but when. Without it, the probability is very high you’ll end up in a situation you don’t understand with no idea how you got there.

  19. 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.
