Distance Protection (21) has many names (Line Protection, Line Distance Protection, Impedance Protection) and is one of the more complicated elements used in protective relaying. The Relay Testing Handbook series explains Line Distance Protection. This bonus animation was created to help relay testers understand distance relay principles. See if you can
A reader submitted a question through the Ask Chris form. I’ve expanded the original question from “what are the differences between relays, contactors and motor starters?” to “What is the difference between contactors, motor starters, relays and circuit breakers?” We’ll look at the history of electrical protection in this post
A friend forwarded me this video because it relates to electricity. It made me laugh. Don’t try this at home. Is it the current or voltage that kills?
