description: The subject of the graduate qualification work is "Modeling the operation of a grounding conductor in a heterogeneous ground under thunderstorm effects". In this work, a simulation of the flowing current from a vertical grounding conductor with a standard lightning voltage pulse under conditions of heterogeneous soil is carried out. Based on the results obtained, the factors influencing the flowing current are determined. The work was carried out using the COMSOL Multiphysics program. A model of a vertical grounding conductor with a length of 2.5, 5 and 10 meters with a radius of 2.5 centimeters was used, installed in an inhomogeneous soil, where the boundary between the soils was at a distance of 1 and 2 meters. The aim of the work was to investigate how the following values affect the flowing current from the grounding conductor: the relative dielectric constant of the first and second soil, the relative conductivity of the first and second soil, the length of the grounding conductor, the distance to the soil boundary and the location of the soil boundary, namely: the horizontal and vertical location of the soil boundary. As a result of the work, the dependences of the flowing current on time were obtained with different combinations of the above factors. At the end of the work, the obtained graphs were analyzed and a corresponding conclusion was made.
