Abstract

The present invention relates to an electric charge dissipation system for a wind turbine blade in compliance with a lightning protection system and / or with the capacity of mitigating dirt problems in wind turbine generator blades. A second object of the invention is the wind turbine blade comprising the electric charge dissipation system. A third object of the invention is a method for dissipating the electric charges in the wind turbine blade.

Description

technical field [0001] The present invention relates to charge dissipation systems for wind turbine blades. The present invention relates to charge dissipation systems compatible with lightning protection systems and / or the ability to mitigate dust problems in wind turbine generator blades. [0002] A second object of the invention is a wind turbine blade comprising a charge dissipation system. [0003] A third object of the invention is a method for dissipating electrical charges in a wind turbine blade. Background technique [0004] In prior art document US2497924 it is known to solve the problem of static electricity on aircraft surfaces. This problem exists in the aircraft industry, including electrical equipment in aircraft and malfunctions when encountering thunderclouds and ice, rain or dust. Also, the aircraft is isolated from the ground. Therefore, it is not possible to have a grounded cable to dissipate static electricity during flight. This system is based on...
