A delta–wye transformer (Δ–Y 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.
In a wye configuration, one end of each of the three windings is connected to form a neutral. A phase is connected to the other end of the three windings. The neutral is usually grounded. The following paragraphs describe three-phase transformers which utilize the delta and wye connections.
In power distribution systems, three-phase transformer configuration directly impacts system reliability and load management. Understanding the trade-offs between Delta and Wye connections enables ...
