PowMagFact Magnitude factor to scale power
calculations
1.000 It can be used during commissioning to
achieve higher measurement
accuracy. Typically no scaling is
required
PowAngComp Angle compensation for phase
shift between measured I & V
0.0 It can be used during commissioning to
achieve higher measurement
accuracy. Typically no angle
compensation is required. As well here
required direction of P & Q
measurement is towards protected
object (as per IED internal default
direction)

All three phase-to-ground VT inputs
are available
k
Low pass filter coefficient for
power measurement, V and I
0.00 Typically no additional filtering is
required
