Function description
Insulation gas monitoring function
14.2.2
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.
14.2.3
Setting guidelines
The parameters for Gas medium supervision SSIMG can be set via local HMI or Protection and
Control Manager PCM600.
Operation : This is used to disable/enable the operation of gas medium supervision i.e. Off/On.
PresAlmLimit : This is used to set the limit for a pressure alarm condition in the circuit breaker.
PresLOLimit : This is used to set the limit for a pressure lockout condition in the circuit breaker.
