description: The paper simulates the coupled electromagnetic field of a vertical grounding rod under the influence of a thunderstorm pulse. The process of current spreading in a ground conductor is investigated using the finite element method in the Comsol Multiphisics program. A model of a 5-meter vertical grounding rod is constructed. The stationary mode of operation of the grounding device (GD) is considered and the static resistance is found, which is consistent with the result obtained according to the analytical formula. The transient mode of operation of the GD is also considered, where the electric and magnetic fields are connected by currents considering the displacement current. A graph of the propagation of an electromagnetic wave along the length of the electrode is obtained. Wave processes in the 5-meter and 20-meter GD in ground with different relative permittivity and electrical resistivity are analyzed.
