Abstract

The results of experimental determination of surface flashover breakdown voltage under high voltage ac and dc for cylindrical G10 are presented. The results are analysed using Weibull statistics and are compared with theoretical field calculations obtained using Ansoft, which is a software package based on finite element analysis. The results show that there is significant improvement of the parameters such as surface flashover voltage and reliability of the results at 77 k over those at 293 K.
