Abstract: A method for repairing or improving a lightning protection system of a rotor blade of a wind turbine having a blade root and a blade tip includes identifying a repair or improvement location in the lightning protection system of the rotor blade. The method includes removing one or more layers of material at the repair or improvement location that form part of a shell of the rotor blade so as to expose existing conductive material in the rotor blade. The method also includes placing a conductive layer of material atop the repair or improvement location such that a root-side edge of the conductive layer overlaps the existing conductive material. Moreover, the method includes electrically connecting the root-side edge of the conductive layer with the existing conductive material and a tip-side edge of the conductive layer of material with the blade tip. The method further includes covering the conductive layer with an outer covering.

Abstract: A wind turbine blade (10, 610) for a rotor of a wind turbine (2) having a substantially horizontal rotor shaft is described. A surface mounted device (70, 70′, 170, 270, 370, 470, 570, 670, 770) is attached to a surface of the wind turbine blade (10). The surface mounted device (70, 70′, 170, 270, 370, 470, 570, 670, 770) is attached to the surface of the wind turbine blade (10, 610) via at least a first attachment part (77, 77′), which is connected to a part of the surface mounted device (70, 70′, 170, 270, 370, 470, 570, 670, 770). The attachment part (77, 77′) comprises a flexible housing (80, 80′, 680, 780) that forms a cavity (81, 81′, 681, 781) between at least the housing (80, 80′, 680, 780) and the surface of the wind turbine blade (10, 610). The cavity (80, 80′, 680, 780) is filled with an adhesive that provides an adhesive bonding to the surface of the wind turbine blade (10, 610).
