Critical feedback on the methods of determining the impact of lightning on power system objects

The methods still use in Romania to assess the protection effectiveness against lightning, derives from physical modeling, on reduced-scale models, of protected facilities and means of protection such as lightning rods and protection conductors. Therefore an analysis of the new methods assessing this problem was necessary. Electrogeometric model (MEG), the developed electrogeometric model (MEGD) or generalized model of triggered leader (MGDL) are analyzed and compared in this article.
