PURPOSE: An arrangement for lightening protection of wind turbine blades is provided to reduce the resistances of blades against rotary moment and improve the efficiency of a wind turbine. CONSTITUTION: An arrangement for lightening protection comprises winglets which extend wind turbine blades that include lightening acceptors in tip end regions thereof. The winglets include additional lightening acceptors. The lightening acceptors are located in the winglets and/or the blades in regions where negative pressure-vortex are created. |
