Operation principle
Insulation gas monitoring function SSIMG (63) is used to monitor gas pressure in the
circuit breaker. Two binary output signals are used from the circuit breaker to initiate
alarm signals, pressure below alarm level and pressure below lockout level. If the input
signal PRES_ALM is high, which indicate that the gas pressure in the circuit breaker is
below alarm level, the function initiates output signal PRES_ALM, pressure below
alarm level, after a set time delay and indicate that maintenance of the circuit breaker is
required. Similarly, if the input signal PRES_LO is high, which indicate gas pressure
in the circuit breaker is below lockout level, the function initiates output signal
PRES_LO, after a time delay. The two time delay settings, tPressureAlarm and
tPressureLO, are included in order not to initiate any alarm for short sudden changes in
