Question 54Electricity & Electronics - QMED

The correct answer is C) periodic cleaning of the air filters or screens. The periodic cleaning of air filters or screens is an important part of routine maintenance for a ship's service alternator. This helps ensure proper airflow and cooling, which is critical for the alternator's efficient and reliable operation. Neglecting to clean the air filters or screens can lead to overheating and potential damage to the alternator. The other answer choices are not directly related to the routine maintenance of a ship's service alternator. Lubricating the exciter slip rings, megger testing of diodes, and changing the pedestal bearing insulation are not typically part of the regular maintenance procedures for this component.
