Computation of electric fields and potential on polluted insulators using a boundary element method

Abstract

The authors present a calculation method for electric fields and potential applicable in the case of a polluted insulator. This method, based on boundary integral equations, is suitable for 3-D geometries and polluted layers. Results obtained by this method are compared with analytical solutions (potential, currents) and with measured values (potential, leakage current).< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
