Hands-on Relay Testing Training

Relay Testing Training Classes

Valence Electrical Training Services has shown its commitment to the high-voltage electrical testing industry with The Relay Testing Handbook series, TechTalk blog, YouTube video series, online training courses, and conference presentations. We also provide hands-on relay testing training classes at your location, or ours.  Relay test technicians who graduate from our classes can answer:

  • How can I test a relay in the shortest amount of time, and make sure it will work when required?
  • What is a protective relay?
  • Where are protective relays used?
  • Why do protective relays need to be tested?
  • What are the most common protective relay functions?
  • How do I test any protective relay or element?
  • What are the most effective test techniques available?

Other protective relay testing training classes are:

  • Test-set or relay specific
  • Four days or longer
  • Based on outdated material

This means that a student in classes from other providers:

  • Only learns one way to test the relay
  • Can become overloaded with too much, or outdated, information that they can’t retain
  • Requires overtime while travelling to and from the training site

Valence used years of relay training experience to create a modern curriculum for today’s relays and test equipment. Our class size, topics, and duration are designed to make sure our trainees retain the information they learn in the class through a combination of theory and hands-on training.

All of the Relay Testing Training Classes from Valence:

  • Can be universally applied to any relay or test-set
  • Are three-days long to:
    • Reduce information overload
    • Help the student retain the information
    • Minimize travel costs and overtime
  • Use modern relays and universal techniques that can be applied to any modern relay test-set or relay test software from any manufacturer
  • Demonstrate multiple techniques to test relays

All of our in-person training classes include post-training services where students can ask follow-up questions, and consult with relay testing experts for help after the courses are complete.

While we focus on ensuring that students graduate with the knowledge and skills they need to become effective relay testers, we understand that recognition is also important. All of our graduates receive a certificate of completion, which can be used with your regulating board.  Each class has been pre-approved for the number of NETA Continuing Education Credits (CTDs) listed in each class description.

The Introduction to Modern Relay Protection Testing class is for relay testers who want to learn the basics including:

  • What is the power system?
  • Why and how protective relays are applied?
  • What are phasors and phasor diagrams?
  • What do these numbers mean in the relaying world? (50/51/67/etc.)
  • How to read and compare single-line, three-line, manufacturer, and DC drawings.
  • How to communicate with relays and test-sets.
  • How to build effective and efficient test plans.
  • How to apply basic relay testing procedures.
  • What is digital relay logic and how do I test it?

We asked former students “What would you tell students who are interested in this relay testing training class?”

If you test relays, I’d be surprised if you found a better course anywhere else. Chris has a stupendous amount of knowledge and is very good at explaining the information

Definitely worth the effort, you will learn not only techniques of relay testing but as well as exemplary professionalism. The courses prepares one to be a good relay tester instead of “Button Pusher” or a mediocre one. Better yet, you might’ve found yourself a field support. Get hold of “The Relay Testing Handbook” by Chris Werstiuk, very good review on related power system theories and excellent guide line for the training course. Bring your own test set. Have a good set of clutter-free stackable test-leads. Bring your own test sheet.

Approach the class with an open mind no matter your background experience.

I would definitely recommend this course. This course strategically goes over ever generator specific protection element in a manner that allows the students to absorb it.

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

I was really impressed with the instructors knowledge of both the test equipment and the relays which we tested. I have been to several advanced relay training courses and this was by far the best yet. It is great that it is given by a tester, for testers. I highly recommend this course to anyone who tests relays no matter what their skill set is.
