3 phase squirrel cage induction motor above 10hp with load and DELTA connected will takes high starting current due to starting torque.When motor start with star connected it takes low current but not reach to its rated efficiency.For this purpose motor above 10 hp started with star and after few second when starting torque reduced it will shifted to DELTA to achieve higher efficiency with control FLC and without loss.
