17.2.2 Application
Gas medium supervision (SSIMG) is used for monitoring the circuit breaker
condition. Proper arc extinction by the compressed gas in the circuit breaker is very
important. When the pressure becomes too low compared to the required value, the
circuit breaker operation shall be blocked to minimize the risk of internal failure.
Binary information based on the gas pressure in the circuit breaker is used as an input
signal to the function. The function generates alarms based on the received
information.
17.2.3 Setting guidelines
The parameters for Gas medium supervision SSIMG can be set via local HMI or
Protection and Control Manager PCM600.
