Abstract
The chapter is devoted to the physical causes of the corona discharge in the elements of the electric power system. The most significant negative consequences of a corona discharge are the loss of electricity, as well as a decrease of its quality due to the appearance of higher harmonics. The cause of this discharge is the presence of an electric field with a significant gradient. Therefore, the section simulates electric fields in the presence of rods with rounded vertices and in the presence of curved interface surfaces. Conclusions are drawn on the influence of the geometry of rods with rounded vertices at the level of maximum electric field strength. A combined technique of mathematical modeling of electric field amplification on the rounded vertices of very long cylindrical rods is given. The calculation of the amplification of the electric field at the tops of long cylindrical rods is carried out.
