Operation Operation Off / On On Function must be On
PowAmpFact Amplitude factor to scale power
calculations
1.000 Typically no scaling is required
PowAngComp Angle compensation for phase
shift between measured I & U
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.

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
