Star-delta starting of motors is not possible in case of____________?
Correct answer: A. single phase motors
- A. single phase motors
- B. variable speed motors
- C. low horse power motors
- D. high speed motors
Explanation
Star-delta starting requires a three-phase motor with accessible stator winding terminals, so it cannot be used with a single-phase motor. It reduces the starting voltage and current by initially connecting the windings in star.
