Answer Posted / hiren bhatt
in star connection line voltage of system is decreased to 1
by square root of 3 is equal to 1/1.73 of line voltage,
thats why in starting motor get reduced voltage asper this
ratio and hence star connection help to reduce effect of
dv/dt to the connected load and hence its insulation and
starting current protected
