I’m reviewing information for the next book in The Relay Testing Handbook series and came across this Youtube channel.
This is a dated, but excellent, video introduction to overcurrent protection (50/51) relays that has some great information to help you understand protective relays.
The video reviews the basics of overcurrent protection and provides detailed information regarding electro-mechanical relays and their functions.

You have to love it when you have become nostalgia…
