N2 - Recently the efforts of working groups from academia, industry and certification organizations around the globe in standardization and testing of wind turbine lightning protection systems have increased significantly, with the result that the expected damage caused by lightning strikes, especially in modern rotor blades with a length of 35 meters and above, has been decreased. As part of this effort, the following research approach is presented in this paper: a theoretical model of different rotor blade lightning receptor configurations with finite element analysis has been developed. In order to validate the results of simulations, experimental tests with a special video system were conducted in a high voltage lab. Also a method of determining the possible breakdown path was assessed. An acceptable correlation between the theoretical results and the experiments in the lab was found.
