Which of the following happens when star-delta starter is used ?
Correct answer: C. Both A. and B.
- A. Starting voltage is reduced
- B. Starting current is reduced
- C. Both A. and B.
- D. None of the above
Explanation
A star-delta starter initially connects the motor in star, reducing each winding's voltage to 1/√3 of the delta value. The reduced voltage consequently lowers the starting current as well.
