one type of starter for three phase squirrel cage motors is
a star delta starter switching the stator windings to star
connection to start ,707 of supply volts across each phase
winding when full speed is reached the stator windings are
then connected in delta connection full supply voltage
across each phase winding.
the inrush current during initial starting is limited with
the reduced voltage thus less current

y we use neutral,all r told its used to for closed path..k its a just used to closed path,in a transmission line y we put same conductor used n both phase and neutral..if we use less than phase conductor in neutral mean we ll reduce cost its right r wrong..if we use mean any problem occur in transmission line..
