Operation principle
Insulation liquid monitoring function SSIML (71) 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.
