Abstract

The invention is directed to a method for making an equipotential bonding connection between two components of a lightning protection arrangement of a wind turbine rotor blade. The method includes providing a wind turbine rotor blade having two rotor blade half shells having respective connection and fastening units connected to corresponding ones of the two components of the lightning protection arrangement. A space is present in the interior of the rotor blade between the two connection and fastening units. A connection conductor is introduced from outside of the rotor blade through a through opening in one of the two connection and fastening units into the interior space of the wind turbine rotor blade. The two ends of the connection conductor are fastened to corresponding ones of the connection and fastening units such that the connection conductor bridges the interior space along an essentially linear imaginary line.
