Lightning threatening wind power plants

   



High or moving objects during a storm can be targeted for destruction by lightning. A research group led by Professor Joan montaña conducted to study the effect of lightning by using high frequency photography. Windmills are a higher risk. There is a direct correlation between the speed of rotation of the blades of the wind turbines and the frequency of lightning strikes in the area.





The length of the blade of a modern wind turbine can reach 60 m and a height of attachment to a mast of 100 m. the Tips of the blades of a wind turbine in a strong wind can move at a speed of several tens of meters per second. Items are usually made of composite materials that are very sensitive to the effects of electrical discharges.

But how to protect wind turbines from lightning, yet no one knows.
