Dirt, dust, grease, oil, films or other contaminants can build up on generator windings and create problems. Visual checks and maintenance that includes the following should be performed by trained personnel routinely.

• Check for movement or loosening of wires
• Inspect and clean all leads, electrical and electronic components
• Check insulation using a megger insulation tester

Actual cleaning procedures range from normal cleaning for dust and dirt to extreme cleaning and recoating for heavy grease, dirt and chemical buildup. A cleaning schedule should be developed based upon application and location. Generally generators should be cleaned.

• Yearly
• During generator overhaul
• Whenever megger test results are unacceptable
• It is important to note that applications in extremely dirty or salty, humid environments may require more frequent cleaning (i.e. rock dust, marine aux., outdoor installations, etc. may require weekly cleaning).
