Identification

Function description
Gas medium supervision
12.2.2

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.
12.2.3

Setting guidelines

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

value
On Function must be
1.000 Typically no scaling is required
180.0 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.
L1L2 Only UL1L2 phase-to-phase voltage is
available
0.00 Typically no additional filtering is required
25 Set minimum voltage level to 25%
3 Set minimum current level to 3%
35.00 Set LV side rated phase-to-phase voltage
495 Set transformer LV winding rated current
