the gas pressure. If the gas pressure in the circuit breaker goes below the levels for
more than the set time delays the corresponding signals, PRES_ALM, pressure below
alarm level and PRES_LO, pressure 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.

Insulation liquid monitoring function SSIML - 71
12.16.2 Functionality
Insulation liquid monitoring function SSIML (71) is used for monitoring the circuit
breaker condition. Binary information based on the oil level in the circuit breaker is
used as input signals to the function. In addition, the function generates alarms based
on received information.
