Abstract
The invention relates to a lightning protection system for a wind turbine blade, where the blade is a shell body made of a composite material and comprises a root area and a tip end. The lightning protection system comprises at least one lightning receptor arranged freely accessible in or on the shell unit surface on or in the immediate vicinity of the tip of the blade, and a lightning conductor made of electrically conductive material extending within the shell body along substantially the entire longitudinal direction of the blade. The lightning receptor and the lightning conductor are electrically connected by means of a connection area. The lightning conductor in its entire longitudinal direction as well as the connection area between the lightning conductor and the lightning receptor are electrically insulated in order to prevent lightning striking through the surface of the blade.
