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 the gas pressure. If the gas
pressure in the circuit breaker goes below the levels for more than the set time delays the
corresponding signals, PRES_ALM, pressure below alarm level and PRES_LO, pressure
below lockout level alarm will be obtained.
The input signal BLK_ALM is used to block the two alarms levels. The input signal
BLOCK is used to block both the alarms and the function.
