Answer Posted / raghavendran.r
I believe that it has got something to do with neutralizing of Zero Sequence components in the power system arising during unbalanced condition.
In star, the zero sequence current flows from the neutral to the phases during unbalanced condition.Where as the Zero seq currents wont be able to circulate in Delta connection as it would get cancelled out.
So I suppose that it could be the reason behind such kind of an arrangement.
But do confirm this answer with any other reference.
