Abstract
This paper investigates the computational electrostatic fields necessary to evaluate the electrostatic comparison of eccentric insulation in power cables. An analysis of the electrostatic fields using the transformation of curved boundaries via the inversion transformation is used to compute the compression of eccentric insulation. The effect of electrostatic pressure on thermomechanical breakdown of eccentric dielectric of power cables during the load cycle program is presented. The relation between the compressive electro-mechanical breakdown due to the electric field strength for eccentric insulation and coaxial cable is discussed and analysed.
