How to Determine Protection Relay Logic Scheme Operation Using Truth Tables

In this video we discuss how to determine the operation of a logic scheme in protection relays by using logic truth tables. Truth tables allow us to see the output of logic for all possible combinations of the inputs to that logic scheme, such that we can be absolutely certain that a logic scheme will behave the way we want it to under all circumstances.

Please cover the ring bus

[@romeroengineering]

Thanks! Will consider it for a future video

[@moe.abedi88]

how to wire this logic? additional devices needed between the relay and CB?

[@derekbutton_320i]

This is all done within the relay.
