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 and the input signal
BLOCK to block both alarms and the function.
