The paper "Wind Generators: Unique Repair Tips" by Chuck Yung, presented at the EASA Convention 2006, provides valuable insights into the repair and maintenance of wind generators, highlighting opportunities for improvement in insulation strength and mechanical construction. Wind power is rapidly growing in North America, with significant installations in 2005 and projections for continued growth. Most commercial wind generators in North America are rated between 660 kW and 1.5 MW, although larger units exist. The paper emphasizes the importance of cost-effective repairs due to the high expense of crane services required to remove generators from tall towers.

The purpose of this article is to provide a simplified explanation of how induction generators work, and what problems we might expect when repairing them. We owe it to our customers to help them avoid these pitfalls. If not, a generator may come back as an unjustified warranty claim.
