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.
Answers. 1  Delta G is the work exchanged by the system and the surroundings. It is just a matter of definition. (Delta H) - T(delta S) implies the energy given by the surroundings to the system, therefore when it is negative it means the system gave energy to the surroundings, and therefore it was a spontaneous process. If it had been defined as T(delta S) - (Delta H) it would have been the opposite.
