16.2 Gas medium supervision SSIMG (63)
16.2.1 Functionality
Gas medium supervision SSIMG (63) is used for monitoring the circuit breaker condition.
Binary information based on the gas pressure in the circuit breaker is used as input signals
to the function. In addition, the function generates alarms based on received information.
