Three-phase Transformers in the Schneider Electric catalog have Delta connected primaries. What if I have a Wye connected service?
Issue:
Delta connected primaries on three phase Transformers

Product Line:
LV Transformers

Environment:
Applies to three phase Transformers by SquareD/Schneider Electric

Resolution:
Delta connected primaries are perfectly suitable for use on Wye services. The contractor uses the 3 phases and ground from the service into the Transformer and does not include the neutral wire. The reason that Wye primaries are not normally recommended is that Wye-Wye and Wye-Delta Transformers have special application issues that must be observed to avoid serious problems. As a result, they are seldom used in the electrical industry. For further information contact your distributor or local SquareD/Schneider Electric sales office.
