Which of the following procedures should be used to maintain a large electric motor during periods of inactivity?

Question 1 of 27070

Which of the following procedures should be used to maintain a large electric motor during periods of inactivity?

🔍 Key Concepts

• Electric motor insulation and how moisture affects it during long idle periods • Differences between cleaning methods (solvent, compressed air, varnish) and preventive protection • Why condensation is a bigger long‑term risk than dust when a motor is not running

💭 Think About

• Ask yourself which option is about preventing damage during storage, not cleaning after operation • Which procedure could improve insulation resistance by keeping the windings dry over time? • Which choices might actually introduce new hazards, such as driving dust deeper into the windings or attacking insulation materials?

✅ Before You Answer

• Identify which option focuses on controlling moisture/condensation rather than just removing dirt • Eliminate any method that could damage insulation or push contaminants further inside the motor • Consider standard shipboard practice for idle generators and large motors—how are they kept dry when not in use?

Spraying a solvent periodically to remove carbon dust.

Compressed air should be blown over areas where dust is deposited.

A thin layer of air-drying varnish should be applied on the windings.

Space heaters should be used to prevent condensation of moisture.
