Function description
Insulation liquid monitoring function
14.3.3 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.
14.3.4 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.
tResetTempLO: This is used for the temperature lockout indication to reset after a set time delay in s.
tResetTempAlm: This is used for the temperature alarm indication to reset after a set time delay in s.
