A synchronous converter can be started______________?
Correct answer: D. any of the above methods
- A. by means of a small auxiliary motor
- B. from AC. side as induction motor
- C. from D.C. side as D.C. motor
- D. any of the above methods
- E. none of the above methodsHire Civil Engineers
Explanation
A synchronous converter has no inherent starting torque, so it may be brought up to speed by an auxiliary motor or started through its AC or DC side as an induction or DC motor. Therefore any of the three methods can be used.
