Abstract
A method of making a wind turbine blade incorporating a lightning protection system includes providing a blade mold; arranging a protruding element in the mold; arranging an electrically conductive layer over the protruding element; arranging one or more structural layers and/or structural components over the conductive layer; consolidating the layers under vacuum to form a blade shell having the conductive layer proximate an outer surface of the shell; separating the protruding element from the blade shell to define a recess with the conductive layer extending into the recess; providing an electrical component adjacent an inner surface of the shell; and electrically connecting the conductive layer to the component. An end portion of the connecting member is housed in the recess such that a surface of the connecting member abuts the conductive layer inside the recess.
