Abstract

The paper deals with the optimization of a spacer for HVDC-Gas-Insulated-Substations (GIS) by means of 2D-axisymmetric field calculation. For high voltage DC conditions the field is mainly controlled by the conductivity κ of the insulation material. Therefore investigations on the influence of volume and surface resistivity on the field distribution of the spacer are made. The field distribution can be improved by a certain resistivity. In addition to the calculations with a constant resistivity of the whole spacer surface, computations with varying resistivities have been made, leading to an even better field distribution. The influence of volume resistivity are also investigated and discussed
