A delta-wye transformer is a type of three-phase electric power transformer design that employs delta-connected windings on its primary and wye/star connected windings on its secondary. A neutral wire can be provided on wye output side. It can be a single three-phase transformer, or built from three independent single-phase units.
For the same load, delta provides higher current than wye, or star. Wye voltage is 1 / 1.732, or 0.577 that of delta. (1.732 is the square root of 3.) This gives a power of â¦ 0.333 for wye, as opposed to delta.ransformers can be connected in Wye (One side of each winding connected to the phase wire and the other connected to neutral or ground) or Delta (â¦ the polarity of each winding connected to the nonpolarity of another winding to form a triangle).
