Aspects of computations of 3D electromagnetic fields near power overhead lines

Popis výsledku v původním jazyce

Computations of three-dimensional (3D) electromagnetic fields can presently be performed by means of a whole range of professional programs, such as COMSOL Multiphysics, ANSYS and Opera. These programs employ the finite-element method (FEM) requiring division of the computed area into volume elements of various sizes. However, a 3D mesh generation and its computation in these programs can sometimes be a problem due to a possible disproportion between the dimensions of conductors in focus and the whole computed area. In such cases, professional programs are either unable to generate a 3D mesh for the input data, or they create a 3D mesh consisting of a great number of elements, resulting in numerous degrees of freedom. This can make the computations considerably time-consuming. The aim of this paper is to demonstrate one possible way to cope with the difficulties described above, namely the application of the integral method. As opposed to the finite method, which requires the generatio
