Whisper 200 wind turbine FYI

This week, one of my Whisper wind turbines apparently suffered a lightning strike.  The symptom appeared as a severely reduced output from the turbine, as though the Stop Switch had been turned on.  After winching the turbine down and disconnecting it from the tower, a Ohmmeter test showed leakage from two of the output wire brushes to the case of the unit.  The case ground path goes through the bottom brush in the brush assy, and the only path for a lightning strike from the case to the mast is through that brush.  There is a bolt securing the brush assy's to the yaw shaft, and a plastic insulator isolating the bolt from the output wire brushes. The lightning arced from the ground brush to the bolt, passing through that plastic insulator tube around the bolt, carbonizing it and creating a carbon resistor path of about 7 ohms on both ends of the insulator tube and effectively grounding two of the three outputs from the turbine.  To avoid a return shipment and a waiting period to Southwest Wind Power Co., I cut a piece of 3/16 inch polyurethane fuel tubing to act as a replacement insulator, and got the turbine back online the same day.  So far, so good.......It's working for me again. The turbine mast is probably the highest structure on most Alt E properties, so I'm thinking that others have suffered this same situation, and perhaps this will help with some diagnoses.  Jon C.
