Insulation gas monitoring function SSIMG - 63
18.2.2 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.
