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