16.3.2 Identification
Function description
Insulation liquid monitoring function
16.3.3 Application
Liquid medium supervision (SSIML ,71) is used for monitoring the oil insulated device condition.
For example, transformers, shunt reactors, and so on. When the level becomes too low compared
to the required value, the operation is blocked to minimize the risk of internal failures. Binary
information based on the oil level in the oil insulated devices are used as input signals to the
function. In addition, the function generates alarms based on the received information.
16.3.4 Setting guidelines
The parameters for Liquid medium supervision SSIML can be set via local HMI or Protection and
Control Manager PCM600.
Operation : This is used to disable/enable the operation of liquid medium supervision i.e. Off / On .
LevelAlmLimit : This is used to set the limit for a level alarm condition in the oil insulated device.
LevelLOLimit : This is used to set the limit for a level lockout condition in the oil insulated device.
TempAlarmLimit : This is used to set the limit for a temperature alarm condition in the oil insulated
device.
TempLOLimit : This is used to set the limit for a temperature lockout condition in the oil insulated
device.
tLevelAlarm : This is used to set the time delay for a level alarm indication, given in s.
tLevelLockOut : This is used to set the time delay for a level lockout indication, given in s.
tTempAlarm : This is used to set the time delay for a temperature alarm indication, given in s.
tTempLockOut : This is used to set the time delay for a temperature lockout indication, given in s.
tResetLevelAlm : This is used for the level alarm indication to reset after a set time delay in s.
tResetLevelLO : This is used for the level lockout indication to reset after a set time delay in s.

2.2.4 Binary quality inputs SENLVLQ and SENTEMPQ have been added for pressure and
temperature sensor signals in order to control alarm and lockout signals. Whenever
there is no sensor, the quality of the binary input will be low. If sensor quality is low,
then lockout and alarm signals will get reset.
