ELECTRIC FIELD NEAR BUNDLE CONDUCTORS

Daniel Mayer - Vít Veselý

   The paper deals with computation of electric field distribution along the surfaces of a system of parallel conductors with various potentials. The method starts from integral equations and the elaborated algorithm is applied to hv and uhv overhead lines with bundle conductors. The results allow evaluating the danger of giving rise to corona (even with respecting the influence of a rough surface of the cable) with all its interference effects. The algorithm was compared with other already published methods with remarkable agreement.

Keywords: hv and uhv overhead lines, bundle conductors, corona, method of integral equations
