What should be included in the performance of routine maintenance of dry-type transformers?
AI Explanation
The correct answer is D) cleaning the windings, if accessible, with a vacuum cleaner or very low-pressure air.
This is the correct answer because routine maintenance of dry-type transformers typically involves periodically cleaning the windings and insulation to remove any accumulated dust or debris. Using a vacuum cleaner or very low-pressure air is a safe and effective way to clean the windings without damaging the insulation. The other options are either incorrect or not directly related to the routine maintenance of dry-type transformers.
