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
Typically no additional filtering is
required
