Identification

Function description
Gas medium supervision
13.2.2

Application

Gas medium supervision (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 shall
be blocked to minimize the risk of internal failure. Binary information based on the gas
pressure in the circuit breaker is used as an input signal to the function. The function
generates alarms based on the received information.
13.2.3

Setting guidelines

The parameters for the gas medium supervision SSIMG are set via the local HMI or PCM600.

Typically no angle compensation is required.
However here the required direction of P & Q
measurement is towards busbar (Not per IED
internal default direction). Therefore angle
compensation have to be used in order to get
measurements in aliment with the required
direction.
