Simulation of Complex Electrode-Spacer Configurations Used in HV Systems for Accurate Electric Field Calculation

摘要

In practice the shape of the electrodes and the spacers in high voltage equipments are so designed that the electric stress on the electrodes, mainly on the live electrode, and on the spacers are well within the limits. This necessitates that the practical contours of the insulators have complex geometries. The complexities are often increased by the constraints imposed by the mechanical considerations in the Gas Insulated Systems (GIS). Suitable techniques are required for accurate yet efficient simulation of such complex geometries. This paper highlights a modified algorithm for computation of electric field distribution by indirect boundary element method (indirect BEM) around a complex electrode-spacer configuration used in practise in high voltage system arrangements.
