Answer / rishad

In a star connection Line Current is Equal to Phase Current. i.e.

Line Current = Phase Current

IL = IPH

Where as in delta line current= 1.732 phase current

Answer / amar

In star, resistance across two terminal become three times as compare to delta.

Answer / anand yadav

The motor starting current can be reduced by following methods;
1. Start the motor without load.
if not possible
2. Use auto transformer starter
or
3. Use soft starter

Answer / k.prakashchandra

The motors are usually designed to run in delta connection i.e. each of the three windings to take line voltage . When you start in star connection , each winding is subjected to phase voltage , Hence the starting current will be less .
