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

Modern relay protection can be extremely complex or relatively simple, depending on the relay model and design engineer. It is possible to use some testing techniques from previous relay generations, but these techniques only test individual elements, which does not guarantee the relay is set correctly or will operate when required.

Most modern relay problems have nothing to do with the actual relay as supplied by the manufacturer. Today’s relay problems occur when the relay has been incorrectly connected to the power system or was set incorrectly by the design engineer. Unfortunately, these problems cannot be detected by traditional relay testing techniques that reprogram the relay in order to get the right test value for the test sheet. Traditional techniques don’t ask the right questions to find the problems that prevent the relay from operating.

Modern relay testers must apply several different skill sets to effectively test digital relays so that they can get the test results they need for their reports, and make sure the relay is properly applied. This class will provide the basic knowledge every modern relay tester should have 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?

Who should take this class?

Anyone who wants to learn more about relay testing, but doesn’t know where to start; or an inexperienced relay tester who has been thrown to the wolves on projects and is tired of winging it.

    :

    Someone should take this course whether they know everything about relays or know nothing about them at all. Anyone could walk into this course and learn something. For those who have low experience with testing relays, this class will start you off on the right path to becoming a great relay tester.

    :

    If someone wants to gain a better understanding of basic protection schemes this is a good starting point.

  3. :

    THE CLASS CONNECTED SOME DOTS THAT WERE A MYSTERY. WELL PUT TOGETHER AND VERY WELL PRESENTED FOR NEW TECHS.

    SIGN UP!

    :

    I would recommend this coarse before any other coarse because it covers information that you need in the beginning of relay testing.

  5. 5 out of 5

    :

    Very well instructed, and great course.
