In the above example of logic implementation, there are two inputs to the AND equations, one is
SF6 Gas low signal and other input is TCS Alarm which is internally generated signal. When
both input signals are active. Then the result of AND equation will be active. This output can be
used to block all protection functions through an external wiring.
