Question 1 of 27070

What should be in included in performing routine maintenance of dry-type transformers?

🔍 Key Concepts

• Dry-type transformer construction and what parts are exposed to air • Safe methods for cleaning electrical equipment • Purpose of insulation resistance testing on electrical machinery

💭 Think About

• Which option could actually damage the insulation or windings of a dry-type transformer rather than help maintain it? • Think about how you would check the condition of insulation over time without taking the transformer apart—what instrument is commonly used? • Which methods listed are more suited to heavy mechanical cleaning versus checking electrical condition?

✅ Before You Answer

• Eliminate any option that could introduce moisture or conductive residue into electrical windings • Avoid methods that could physically damage insulation or force debris deeper into the windings • Identify which method is specifically intended to measure insulation resistance rather than just clean surfaces
