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.
All courses are completed online. You need:

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.
We are working hard to build a complete relay training program and have the following courses available, with more on the way:
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
Three-Phase Electric Power Systems

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 firstname.lastname@example.org or 888-300-6382.
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!

We are ready to get started on the next course about the electrical fundamentals that every relay tester should know. Please help us out by commenting on the following post
Online seminars are a series of videos that you can watch to learn more about relay testing. They do not have exercises of quizzes.
This online protective relay testing seminar follows Chris Werstiuk (author of The Relay Testing Handbook) as he shows you the basic skills you need to test any digital relay with any modern test-set. Learn how to test protective relays with online videos that are broken down into logical chunks that you can watch at any time and in any order so that you can fit this series into your busy schedule.
