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
Transformer vector groups can be a difficult concept to understand. I was lucky because the transformer ratio test-set I used for the first couple of years in my career allowed me to make three-phase connections, but it was really a single-phase tester and I had to change the connections one
