If a shipboard AC generator experiences a failure to produce a voltage, what may be the cause?
Official USCG Answer & Rule Citation
Correct Answer: Option D — an open in the rotor field circuit
An open circuit in the rotor field stops magnetic flux generation, preventing electromagnetic induction in the stator windings and causing the AC generator to produce zero terminal voltage, a classic failure mode covered in IEEE 45.
