DOL starting of induction motors is usually restricted to_____________?
Correct answer: A. low horsepower motors
- A. low horsepower motors
- B. variable speed motors
- C. high horsepower motors
- D. high speed motors
Explanation
DOL starting draws a large inrush current, which can cause excessive voltage drop in the supply network. It is therefore generally used only for low-horsepower motors whose starting current is acceptable.
