Question

Choose a wrong choice on d.c. machine regarding compoles or compensating winding

• A. Compoles neutralize reactance voltage
• B. Compensated winding is connected in series with armature
• C. Compole winding neutralize de-magnetizing effect of armature reaction
• D. Compensating winding neutralize cross-magnetizing effect of armature reaction

Hint:

Compoles are series-connected; compensating windings are parallel and mounted on pole faces.

Answer 1

The Correct Option is B

Compensating windings are connected in parallel with armature, not in series. They are embedded in pole faces to counteract armature reaction.
