What happens if the wind turbine is struck by lightning?
Most wind turbines of today include lightning protection. Typically, the lightning protection installed in the blade tip discharges the lightening inside the rotor blades, going around the nacelle and then down the tower thereby diverting the electrical charge away from the machinery. Very rarely does the lightning destroy a turbine completely. Damage, if any, is usually confined to a blade or blade tip and can be repaired or replaced easily.
