A cumulatively compounded long shunt generator when operating as a motor would be____________?
Correct answer: B. deferentially compounded long shunt
- A. cumulatively compounded long shunt
- B. deferentially compounded long shunt
- C. cumulatively compounded short shunt
- D. differentially compounded short shunt
Explanation
When a compound generator operates as a motor, the armature current reverses relative to the series-field connection, reversing the series-field mmf's effect. Thus cumulative compounding becomes differential, while the long-shunt connection remains long-shunt.
