Fayette turbine generator in Dayton for repairs 2011.12.21

The wind keeps blowing, the turbine never moves.

The question Fayette school superintendent Russ Griggs hears most often is about the non-functioning wind turbine on the school property.

The 250kW unit went out of service in early October and was disassembled as technicians tried to track down the cause of the malfunction.

The 3,300 pound generator was removed and transported to the Koontz-Wagner electrical contractor facility in Bryan, but later moved to the company’s Lima location for warranty work to begin. Due to damage inside the generator, the equipment must be completely rewound.

The work is expected to be complete by Jan. 6 and the generator will be placed back in the turbine tower soon after that, depending on weather conditions and the availability of a crane. When the equipment was disassembled, the turbine company brought in a large crane from Cleveland.

A short circuit put the turbine out of operation and engineers first suspected a problem with the cable that transports power from the generator down the tower. 

No problems were found with the cable and engineers are now convinced that faulty insulation in the generator caused it to burn out.
