Abstract :
The application of synthetic resins as dielectric materials in the design and construction of switchgear originated early in this century. Since then a very large and ever widening number of materials and their compounds have been developed. The authors consider flashover tests which have been carried out to compare the performance of various polymeric formulations and relate these results to the chemical structure of the resin tested. There are many factors which influence surface flashover performance and these are outlined by the authors
