14.16.6 Operation principle
Insulation liquid monitoring function SSIML is used to monitor oil level in the circuit
breaker. Two binary output signals are used from the circuit breaker to initiate alarm
signals, level below alarm level and level below lockout level. If the input signal
LVL_ALM is high, which indicate that the oil level in the circuit breaker is below
alarm level, the output signal LVL_ALM, level below alarm level, will be initiated
after a set time delay and indicate that maintenance of the circuit breaker is required.
Similarly, if the input signal LVL_LO is high, which indicate oil level in the circuit
breaker is below lockout level, the output signal LVL_LO, will be initiated after a time
delay. The two time delay settings, tLevelAlarm and tLevelLockOut, are included in
order not to initiate any alarm for short sudden changes in the oil level. If the oil level
in the circuit breaker goes below the levels for more than the set time delays the
corresponding signals, LVL_ALM, level below alarm level and LVL_LO, level
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.
