Online Protective Relay Training

Today’s relay tester has to perform more work in less time, and typically has very little support to help them test modern digital relays that become more complex every year. We created The Relay Testing Handbook series as a practical reference guide for the modern relay tester, but studies have shown that most people must apply multiple learning styles before they fully understand a topic.

Each course in this online protective relay training series is based on a topic in The Relay Testing Handbook, and hits all three key learning styles described below to ensure you retain the information and can start using it immediately in your day-to-day activities.

  • You can read about the topic with excerpts from The Relay Testing Handbook.
  • You will listen to a narrator while watching videos that discuss the topic in greater detail. You can learn at your own pace with controls that can pause, rewind, fast-forward, etc.
  • You will use our interactive exercises that simulate the topic using the most realistic situations possible to help you learn by doing.

All courses are completed online.  You need:

  • A good internet connection
  • Speakers or headphones
  • 10 – 15 minutes per activity
  • A printer to print your certificate of completion when the course is complete

How do I take the course?

After you purchase your course at you can take a course by:

  • Logging in to your course through the login page
  • Choose the course you wish
  • Choose the topic you wish to take
  • Watch the video(s), take a quiz, or work through an interactive exercise
  • The course manager tracks your progress and you can start and stop whenever you wish
  • Take a final quiz when you complete the course.  If you get more than 80% correct, you can print a certificate of completion to receive continuing education credits.

Our online protective relay training courses are designed to:

  • Allow you to choose the topics most important to you
  • Complete the courses at a location and time convenient for you and your schedule
  • Focus on the skills you need to become a better relay tester
  • Be universally applied to any relay or test-set

Each of our online relay training courses has the following structure:

  • An introduction to the course topic with excerpts from The Relay Testing Handbook series
  • A video series describing the topic with animations and examples
  • A series of exercises to help you master the topic through real-world examples
  • A quiz with real-world questions to see how much you’ve learned taking the course
  • A certificate of achievement that can be used for continuing education credits

All of our online training videos use Flash technology that should work on all Windows computers or tablets. You can view the course on Android tablets with the Dolphin Browser for Android, or on an iPad with the free Puffin Web Browser.  We found that the paid version of Photon Flash Player for iPad had better performance on an iPad.

Available Online Protective Relay Training Courses

We are working hard to build a complete relay training program and have the following courses available, with more on the way:

Course 1-1: The Three-Phase Electric Power System, 4 CTDs

Protective relays are constantly looking at the three-phase electric power system while on a hair trigger, waiting to detect a fault and isolate that fault from the rest of the electrical system. You could test electro-mechanical relays without a true understanding of three-phase electric power system because they used magnets and mechanisms to model a small part of the power system while looking for a specific problem. Testing electro-mechanical protective relays was more about getting mechanisms to move and the relay tester could follow some simple steps to make the relay mechanisms move for testing.

It is possible to carry this philosophy forward into digital relays by re-programming the relay when testing each element, but these tests only prove that the relay could theoretically operate if required.  A relay tester who understands the three-phase electrical system can build test plans that test the entire relay as a whole to make sure the relay operates when required for more effective and efficient test procedures.

We will cover the following topics in this lesson to give you a foundation in three-phase electrical theory to help you become a craftsman instead of a button-pusher:

Introduction to Electrical Fundamentals and Frequency

  • How electricity is created
  • What is a cycle
  • How to count cycles
  • Understand how frequency and cycles are related
  • Converting cycles to seconds
  • Converting seconds to cycles
  • Converting cycles to cycles

Three-Phase Electric Power Systems

  • How three-phase electric power systems are created
  • How to determine what kind of three-phase electric power system is being generated
  • How to change one kind of three-phase electric power into another

This online training course is eligible for 4 NETA Continuing Technical Development Credits (CTDs). NETA Certified Technicians (Level III and Level IV) are required to earn a minimum of 48 CTDs every three years to maintain their certification. For more information about the CTD program and requirements, please contact the NETA office at or 888-300-6382.

Course 1-2: Phasor Diagrams for Relay Testers

Waveform diagrams contain every detail of an electrical system, but that information can be difficult to understand without a lot of effort. Phasor drawings take the complex information embedded in waveform drawings and convert it into phasor diagrams so that you can see the most important information about an electrical system at a glance. Understanding phasor drawings is probably one of the most important skills that a relay tester must have to be successful!

Take this course to learn these topics:

Understanding Phasors and Creating Phasor Drawings

  • What are Phasors?
  • How to Draw Phasor Diagrams
  • Drawing Phasors with Different Scales

Create and Understand Phasor Diagrams Used by Different Relay and Test-Set Manufacturers

  • Drawing Phasors with Lagging Angles (Megger and GE SR)
  • Draw Phasors with Positive Angles (Doble and Manta Test Systems)
  • Draw Phasors with Negative Angles (GE UR)
  • Draw Phasors with Positive and Negative Angles (Omicron and SEL)
