A rotary converter operates at a______________?
Correct answer: B. high power factor
- A. low power factor
- B. high power factor
- C. zero power factor
- D. none of the above
Explanation
A rotary converter normally operates with a high power factor, especially when its excitation is properly adjusted. Its power factor can be varied somewhat by changing field excitation, but it is not inherently a zero- or low-power-factor device.
