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.
There is 120v from any phase to ground (neutral) with each winding at 120v, but 208v (120 x 1.73) between phases. The 480/277v Y system is connected the same way: 480v line-to-line and 277v line-to-ground. Now, back to our as-of-yet ungrounded Delta system for a moment.There are two ways of grounding a Delta system.uestion about difference between wye and delta. I've been doing commercial and industrial work for a couple of years now, mostly piping and small installations for a contractor. I'm new to the trade and still trying to understand everything.
