What is SF6 Gas Loss Circuit Breaker Logic about?

This document discusses using CFC logic to block tripping signals from a protection device and only generate an alarm if SF6 gas levels in a circuit breaker fall low. The CFC logic uses a NEGATOR gate and AND gate to ensure the general trip signal is only forwarded if there is no SF6 gas loss warning. It also notes the PLC layer used must be PLC_BEARB since a general trip signal needs to be blocked.
