Abstract: A wind turbine blade comprising a blade body, at least three electrically conductive elements comprising conductive material, said conductive elements optionally comprising at least one lightning conductor, at least one spar cap, and at least one heating arrangement, and a potential control arrangement, wherein the at least three conductive elements have longitudinal axes that are essentially codirectional with a longitudinal axis of the blade body. The potential control arrangement comprises a plurality of coupling devices, each of which coupling at least two of said conductive elements, each coupling device and being positioned at predetermined locations with respect to a blade axis being a longitudinal axis of the blade body.

Abstract: A blade for a rotor of a wind turbine, said blade comprising a blade body element provided with a carrier surface to accommodate a heating element, an electrically conductive, elongated and substantially planar heating element disposed upon the carrier surface to extend longitudinally substantially along at least the leading edge of the blade preferably at least about 50% of the length of the blade, more preferably at least about 60% and most preferably at least about 70% respectively, an electrical power supplying conductor element located at one end of the heating element, the conductor element substantially extending over the width of the heating element on both sides thereof and electrically coupling thereto, and a joint structure comprising at least one electrically conductive joint element and substantially covering, on both sides of the heating element, the portions of the electrical conductor element that extend over the width of the heating element, wherein said blade preferably contains an instance

Abstract: A conductor joint for joining a copper conductor to a fiber-structured heating element whose dimensions are length (L)>>width (W)>>thickness (T), and which heating element comprises carbon fiber strands, wherein the copper conductor is transversely disposed to the longitudinal direction (L) of the heating element to form a layered structure in the thickness direction (T), on both sides of the heating element, the copper conductor comprising strands separable from each other.
