Insulation gas monitoring function SSIMG

Identification

Function description
Insulation gas monitoring function

Application

Insulation gas monitoring function (SSIMG) is used for monitoring the circuit breaker
condition. Proper arc extinction by the compressed gas in the circuit breaker is very
important. When the pressure becomes too low compared to the required value, the
circuit breaker operation gets blocked to minimize the risk of internal failure. Binary
information based on the gas pressure in the circuit breaker is used as input signals to
the function. In addition to that, the function generates alarms based on received
information.

Insulation liquid monitoring function SSIML

Identification
Function description
Insulation liquid monitoring function
Application
Insulation liquid monitoring function (SSIML) is used for monitoring the circuit
breaker condition. Proper arc extinction by the compressed oil in the circuit breaker is
very important. When the level becomes too low, compared to the required value, the
circuit breaker operation is blocked to minimize the risk of internal failures. Binary
information based on the oil level in the circuit breaker is used as input signals to the
function. In addition to that, the function generates alarms based on received
information.
