Answer Posted / manish kumar
in a star connection, phase voltage Vph = VL/ (3)^1/2.
1--Since the induced emf in the primary winding of an alternator is directly proportional to the number of turns, a star connected alternator will require less number of turns than a delta connected alternator for the same voltage.
2-- it also requires less insulation bcz its phase is less.
3-- it also help to reduce third harmonic ...
