Abstract: A conductive connection between a Carbon Fiber Reinforced Polymer (CFRP) element and one or more down conductor(s), the CFRP element being electrically conductive and has a face. The conductive connection including an interface conductive patch provided on the face of CFRP element for electrically connecting the CFRP element with the interface conductive patch, the interface conductive patch is electrically connected with the one or more down conductor(s).

Abstract: A lightning protection system for a wind turbine blade having-a structural element made of fiber reinforced polymer (FRP). The lightning protection system includes a first down conductor extending from a tip end to a tip connection block and a second down conductor extending from the tip connection block between and along the structural element and a pressure side towards a root connection block. A third down conductor extending from the tip connection block between and along the structural element and a suction side towards the root connection block. The second down conductor includes a first expanded foil or a first mesh and the third down conductor includes a second expanded foil or a second mesh. The first expanded foil or first mesh and the second expanded foil or second mesh include a plurality of conductive connection points arranged in the vicinity of the tip and root connection blocks.
