13.16.6 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,
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.
