The article is devoted to the development of a mathematical model of an insulator breakdown and the methodology for assessing the development of a breakdown. The main calculation expressions are presented in the article. The design of a real insulator (the outdoor voltage insulator of 35 kV type IOSK 3/35 UHL1) is presented as an example of the technique applicability. The datasheet of this outdoor isolator was used to verify the mathematical model and the results of numerical simulation. The results of numerical simulation and the outdoor insulator breakdown voltage are presented in the article. Numerical simulation was carried out in Comsol Multiphysics software. The obtained results can be applied in the engineering design of outdoor insulators and elements of electrical constructions.
