480v Deltum Wye Transformer Wiring Diagram

The wye connected secondary allows single phase load to be distributed among the three phases to neutral instead of being placed all on one winding as with a four wire delta secondary. Three phase transformer connections and basics likewise for a delta star dy connected transformer with a 1 1 turns ratio the transformer will provide a 1 3 step up line voltage ratio. Note that these phase angles are referring to positive sequence voltages.
