Therefore, if a building is struck by lightning, the architectural part of that building may be destroyed due to the influence of high pressure and temperature, and electrical equipment in the building may be damaged by the field. electromagnetic field of induced lightning currents, and people can be injured if they are near the point of lightning discharge.
