Features of estimating of lightning protection and grounding electrode based on the family of lines of force in electric field

Paper presents statement of problem and the results of mathematical modeling of different schemes of lightning protection system (LPS) on example of launch pads and steel towers of power transmission lines (PTL). The method of mathematical modeling based on solving an elliptic equation (method MMSEE) with respect to the electric flow function is used for the calculation of family of force lines of electric field. The features of the applied MMSEE for problems of practical importance with a goal to calculate the electric force lines with respect to the grounding electrode near the buried part of a reinforced concrete pole are presented at the condition of rain.
