description: In this final qualifying work highlights the study of lightning protection of a 330 kV overhead line, protected by a lightning protection cable and linear arresters. In the course of the work, the necessary theory was considered, and the necessary calculation models of the overhead line section were obtained in the EMTP-RV program, such as: a line model unprotected by arresters, a line model protected by an arrester set to phase A, a line model protected by arresters, installed on phases A and C, as well as a model of a line protected by a spark gap installed on phase A, and taking into account the dynamic properties of its current-voltage characteristic. As a result of evaluating the effectiveness of lightning protection of overhead lines, it was found that the level of lightning resistance is strongly influenced by the grounding resistance of overhead lines. It is possible to achieve optimal lightning protection of the line by installing line arrester on phases (the number of protective devices must be selected for economic reasons), the dynamic properties of the CVC of a linear arrester have an insignificant effect on the level of lightning resistance.
