Answer Posted / ashish
from generating alternator four wires comming, three are
phase(R,Y,V)& one is nutral which is grounded by the use of
nutral grounded transformer near to transformer used for
step up the generating voltge hence after generation we have
three phase so we use star delta transformer(step up) for
transmission & in delta three wire required & at
distributing end delda star transfomer(step down) is used so
four wire are required three phase & one nutral
