POTENTIAL AND ELECTRIC FIELD CALCULATION OF 330KV ICE-COVERED COMPOSITE INSULATORS USING THE FINITE ELEMENT METHOD

摘要：

The main objective of this paper is to compare the flashover performance of five ice-covered composite insulators with different profiles by calculating the values of potential and electric field along the composite insulators using the finite element method. Comsol, a very powerful commercial software is used to do the modelling and simulation. The results show that the layout of the big sheds, with or without the big sheds have a obvious effect on the distribution of potential and electric field of the composite insulators covered with ice. The calculation results are also compared with the experimental results carried out in the artificial climate chamber with good concordance.
