= PhaseVTSecondary / PhaseCTSecondary, where PhaseVTSecondary and
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.
