Abstract

The paper presents a method of numerical modelling of electrical field distribution in three-dimensional systems, with the use of Fredholm´s integral equations of 1st and 2nd orders. The mathematical model enables analysis of high voltage systems in linear, isotropic, homogeneous or partially heterogeneous systems. In this method each surface is divided into N planar elements and approximated by function z=ax+by+c. Calculations are executed for the system three-phase rectangular shielded busways with air insulation
