- 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:
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

Not sure if online training is right for you?
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.
