Question

how much current a star connection a phase induction motor draws in the start as compared to a delta connected motor?​

Answer 1

Answer:

The star-delta method is usually only applied to low to medium voltage and light starting Torque motors. The received starting current is about 30 % of the starting current during direct on line start and the starting torque is reduced to about 25 % of the torque available at a D.O.L start.
