Operation principle
GUID-359458EA-FFAA-4A44-A8E8-9469CA069C80 v7
Gas medium supervision SSIMG is used to monitor the gas pressure in the circuit
breaker. Binary inputs of gas density SENPRESALM, SENPRESLO, and gas
pressure signal SENPRES, are taken into account to initiate the alarm PRESALM
and the lockout PRESLO. When SENPRES is less than
PresAlmLimit
or binary
signal from CB SENPRESALM is high, the gas pressure alarm PRESALM will be
initiated. Similarly, if pressure input SENPRES is less than
PresLOLimit
or binary
signal from CB SENPRESLO is high, PRESLO will be initiated.
There may be sudden change in pressure of the gas for a very small time, for which
the function need not to initiate any alarm. To avoid the intermittent alarm, two
time delays
tPressureAlarm
or
tPressureLO
have been included. If the pressure
