Electrical Engineering XYZ MCQs
Which of the following is example of the stator faults:
- Failure of excitation
- Over-current
- Inter-phase faults
- All of the above
Correct answer: 3. Inter-phase faults
Explanation: These faults occur between the phases of the stator winding. It could be due to short circuits or insulation breakdown between phases. Inter-phase faults can cause unbalanced currents and voltages in the stator windings, leading to overheating and potentially damaging the stator.
