Introduction to Relay Testing


Introduction to Relay Testing

Each of the topics below will introduce you to relay testing. I started out testing relays much like everyone else does, but I soon realized that normal test techniques would never find the common problems in digital relays.  Most of these problems were found by accident as you will see in these videos.

If you watched the complete video series when you signed up to our mailing list, these are the same videos and you can skip them if you wish.  You will have to mark every lesson and topic complete if you want a certificate at the end of the course. Marking lessons and topics as complete as you finish them also helps you keep track of your progress.

Feel free to ask any questions you think of in the comment section of any topic. Don’t be shy! If you’re thinking it, someone else is probably thinking the same thing but doesn’t want to look stupid. I want you to become the best relay tester possible, so I hope you participate and ask any questions that arise as you watch these videos.

No. All the videos are online-only.


Hi Chris,
How do you use a RF signal Generator to shift 120VAC? I would like to try phase shifting using this method. Most of the signal generators I’ve seen online are low magnitude voltages. Thanks!

Unfortunately, you’re asking about equipment that was old in 1997. I have no idea where my boss got it from, but it worked for the task.
