Abstract

A hybrid technique combining the charge simulation and boundary element method has been employed to solve the problem in question. In this model the influence of tower frameworks and of the apparatus construction is taken into account. The basic boundary integral equations are presented and the computer program is briefly described. Selected numerical results concerning a 400 kV outdoor substation are given. The numerical technique and the computer program can be a useful aid for designers of electric power objects as well as for environmental protection authorities. In the near future the program will be applied in a commercial software package for the electric and magnetic-field computation near HV installations.
