What statement is true concerning the use of compensating windings in DC generators?

Correct Answer: Option B — These windings are wound on the main field pole pieces and are designed to counteract armature reaction associated with heavy loads and minimize field distortion.

Compensating windings consist of conductors embedded in the main pole faces and connected in series with the armature. They directly oppose and neutralize cross-magnetizing armature reaction forces under heavy marine electrical loads, preventing severe magnetic field distortion and flashover.
