Z
= PhaseVTSecondary / PhaseCTSecondary, where PhaseVTSecondary and
BASE
PhaseCTSecondary are the secondary nominal voltage and the secondary nominal current of the
distance source. In case multiple CT inputs are summed as one source current and mapped as
the distance source, use the PhaseCTSecondary value from the CT with the highest primary
nominal current.
Distance source is specified in setting under
GROUP 1(6) > DISTANCE
PhaseVTSecondary and PhaseCTSecondary are specified in setting under
