Best answer
  1. At start motors draw more than the motors rated current.This may lead to unnecessary tripping of the motor and the increased current at start causes wear on switch gear.
  2. The motor is started in the star mode which reduces the voltage across each phase of the motor as in star VPH = 3 VL.As the voltage across each phase is reduced, the current in each phase will also be reduced.
