Abstract
Provided is a stepped conductivity arrangement between a carbon-based element and a down conductor of a wind turbine rotor blade, which stepped conductivity arrangement includes a transition interface arranged to electrically connect a first electrically conductive part and a second electrically conductive part, wherein the first electrically conductive part extends from the down conductor, the second electrically conductive part extends from the carbon-based element, and wherein the electrical conductivity of the transition interface decreases in the direction of the second electrically conductive part. The embodiments further describe a wind turbine rotor blade comprising such a stepped conductivity arrangement and a method of providing such a stepped conductivity arrangement.
