How it Works: This online seminar contains over 30 hours of videos (usually less than 15 minutes each) that you can watch at your own pace in any order with an internet connection. You have unlimited, 24/7 access to all the videos with no expiration date. Each video has closed captioning, fast-forward/rewind/play speed controls, and […]

In this seminar, you’ll get to look over my shoulder as I test modern digital relays from start to finish with different test-sets, using everything I’ve learned from over 20 years of relay testing. You’ll learn the basic skills you need to test any digital relay with any modern test-set, how to perform each testing […]

Protective relays are on a hair trigger as they constantly look at the three-phase electric power system and try to decide whether the system is normal, or under fault conditions. If they detect a fault, they will attempt to isolate that fault from the rest of the electrical system. Electro-mechanical relays use magnets and mechanisms […]

We discussed how waveforms and frequencies are created in the high voltage electrical world in our first online protective relay training course, The Three-Phase Electric Power System.  Waveform drawings depict every detail of a power system, but you have to be a special kind of person to look at a waveform drawing and accurately understand what […]
