Researchers in Spain are using high speed video to document high voltage streamers and leaders originating from wind turbine blades. The data indicates that high voltage streamers/leaders occur roughly every 3 seconds as the blades rotate and these events can last minutes or hours. The wind turbine blades do not need to be directly near an active storm as the streamers/leaders can appear while the storm is several kilometers away.
This research provides terrific insight into the high voltage environment that wind turbines operate in.
