Give reasons as to why a star delta starter is preferred with induction motor

  

Answers


Amos
- Starting current is reduced 3-4 times of the direct current due to which voltage drops and hence it causes less losses.
- Star delta starter circuit comes in circuit first during starting of motor, which reduces voltage 3 times, that is why current also reduces up to 3 times and hence less motor burning is caused.
- In addition, starting torque is increased and it prevents the damage of motor winding.
