Abstract :
Laboratory methods of generating fast transient overvoltages are discussed in this paper. The results of breakdown studies carried out with a transmission line model generator using plastic materials is presented. The breakdown is observed to be a fast front phenomenon and the electrode effects are critical. The magnitude of the breakdown voltage is one order higher than the corresponding AC and DC values
