Answer Posted / arpit sood
one of the reason according to me should be that a motor
with star connection draws less starting current (5-8 times
less)
so if the motor is HV then there will be less voltage
fluctuation and less heating of the insulation of the motor
at starting
so the motor is better protected and does not start with a jerk
but generally the large motors are designed for delta
connection due to more mechanical power ( 3 times more than
the star connected) so there is need of auto transformer
starting
