PowAmpFact Magnitude factor to scale power
calculations
1.000 Typically no scaling is required
PowAngComp Angle compensation for phase
shift between measured I & V
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.

Selection of measured current
and voltage
L1L2 Only UL1L2 phase-to-phase voltage
is available
k Low pass filter coefficient for
power measurement, V and I
0.00 Typically no additional filtering is
required
