Star delta starter with induction motor-
Why star delta starter is preferred with induction motor?
Star delta starter is chosen with induction motor due to follow reasons:
• Starting current is reduced 3-4 times of the direct current due to which voltage drops and therefore it causes fewer losses.
• Star delta starter circuit come in circuit first during starting of motor, which reduce voltage 3 times, that is why current also reduces up to 3 times and hence a smaller amount motor burning is caused.
• In addition, starting torque is increased and it prevents the harm of motor winding.
