When a generator is stored for any length of time moisture condenses in the windings. Minimize the condensation by providing a dry storage space.
To remove moisture caused by high humidity or dampness, dry the generator by one of the following methods:
- 1. Place the generator in an oven and bake at a temperature not above 185°F (85°C) for four hours.
If an oven is used for drying, use a forced air type rather than a radiant type. Radiant ovens can cause localized overheating.
- 2. Enclose the generator and heating lamps in canvas to raise the temperature. Leave an opening in the top for the moisture to escape.
- 3. Pass a low voltage current through the windings to raise the temperature of the windings to 185°F (85°C).
If there is a possibility the insulation resistance has deteriorated to a dangerously low level, contact your Caterpillar dealer.
