Influence of multiple overlapping of isolation on line support on formation of lightning overvoltages has been shown. Ambiguity of determination of lightning current dangerous parameters at the fixed length of its front has been revealed

Results of storm activity registration in the Kola Peninsula

Results of storm activity registration processing in the Kola Peninsula during 2013-2014 have been given. Considerable fluctuations of storm activity and unevenness of lightning discharges distribution across the region territory have been noted. It has been proposed to use a cloud-to-ground discharge density indicator taking into account their distribution in the region at an assessment of lightning protection efficiency of power generation facilities in areas with low thunder-storms intensity
