Three-phase circuit: Why Z_Ye is parallel with Z_Δ?

[QUOTE="The Electrician, post: 6042569, member: 101272"] It's true that the circuit doesn't require a 4th wire, but the OP is having trouble seeing why the two wye subcircuits are in parallel. Adding a wire between the center nodes of the pre-existing wye (composed of Zy) and the wye resulting from the delta-wye conversion of ZΔ will make it clear why each element of one wye is in parallel with the corresponding element of the other wye. This wire will carry no current because of the symmetry, so adding it doesn't change the behavior of this very symmetrical circuit. In a circuit without this symmetry, adding this 4th wire would probably change the circuit behavior. [/QUOTE]
