  Therefore, the zero sequence impedance of a transformer depends on the winding connections. In the case where one side of a transformer is connected grounded-wye, and the other side is delta, circulating zero sequence currents can be induced in the delta winding. In that case, the zero sequence impedance "looking into" the transformer is ...

  grounded-wye transformers These transformers have one end of the winding brought out through insulated H.V. bushings and the other end connected internally to the tank. A substantial and thoroughly reliable ground connection should be made between the tank and a low resistance ground through a conductor of adequate cross section.

  a. Connect 3 phase transformer primaries in delta. Do not use wye primaries except in special cases because of “problem connections”. When wye primaries are used, special consideration must be given to the grounding connections and the type of core/coil construction to prevent tank overheating, voltage and load balance problems. 4.
