delta and wye
Impedance Values. The percent impedance values depend on various factorsincluding the number of windings, particular phase, high and low voltage ratings, transformerkVA rating, and the insulation medium and cooling class. In general, impedance values increasewith higher voltage and kVA ratings. For most purposes, the impedance of power transformersmay be considered equal to their reactances because the resistance component is negligible.
so it doesn't have any relation on Delta or Wye.
