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.
Sewer wye connections are available in various types of material including polyvinyl chloride (PVC) and vitrified clay pipe (VCP) material, but typically, these sewer lateral wye materials are made of the same material as the sewer main line (i.e. a VCP sewer main will have a VCP material wye sewer lateral connection as well).
