17.2 Gas medium supervision SSIMG (63)
17.2.1 Identification
Function description
Insulation gas monitoring function
17.2.2 Application
Gas medium supervision (SSIMG ,63) 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.
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.
TempAlarmLimit : This is used to set the limit for a temperature alarm condition in the circuit
breaker.
TempLOLimit : This is used to set the limit for a temperature lockout condition in the circuit
breaker.
tPressureAlarm : This is used to set the time delay for a pressure alarm indication, given in s.
