The Fayette school wind generator is back in action for the first time since early October.
A malfunction took the turbine out of service and efforts got underway to track down the problem. Engineers addressing the problem finally concluded that faulty insulation inside the generator caused the unit to burn out.
After the generator was rewound at a facility in Lima, it was returned to Fayette and lifted into place with a crane last week. An initial problem was straightened out through communication with the turbine company in the Netherlands and the unit was back in operation Jan. 11 and once again producing power.
Fayette superintendent Russ Griggs said another improvement was made to prevent the yaw motors from freezing. The problem prevented the turbine from probably turning into the wind.
A special boot was devised to fit over the motor—an improvement over the do-it-yourself approach involving heat tape and insulation.
The cost of repairs was covered by a warranty.
As of Friday, the turbine had produced 99,150 kilowatt hours of power since it went into service in January 2010.
