DRY Type Transformer Maintenance

The life of your dry type transformers can be improved with proper maintenance. An inspection and maintenance schedule should be established to maximize the life of this equipment. Evidence of rusting, corrosion, and deterioration of the insulation, varnish or paint should be checked, and corrective measures taken. Auxiliary devices should be inspected and serviced during these inspections.

Windings should be inspected for contaminants, especially on insulating surfaces or where they could restrict air flow. Check for loose connections, condition of tap changers, terminal boards and for the general condition of the transformer. Check for signs of overheating and tracking or carbonization marks.
