description: The aim of the thesis is the determination of the main acting factors that affect the shielding effect of grounding devices under lightning impact. Grounding devices usually consist of a number of grounders, which can lead to the shielding effect of the spreading current. We simulated 2D modeling of the one vertical grounding electrode and 3D modeling of the vertical grounding electrodes at COMSOL Multiphysics software. For analyzing the working of the grounding systems under lightning impact we used finite element modeling of the electromagnetic fields. We identified the main acting factors which affect the shielding effect of the vertical grounding electrodes under lightning impact according to a comparison thorough analysis of the results of the modeling of one and the number of the electrodes. In this case, factors such as different soil parameters, the distance between the electrodes, and the placement of the electrodes determined as the main influencing factors were examined. The results were compared by examining the electrodes at different distances and soil parameters.
