Abstract: The results of experimental study of streamer and spark processes under a standard lightning voltage pulse are shown for different degrees of electric-field nonuniformity in sphere–plane and sphere–sphere electrode systems. The possibility of introducing similarity relations for streamer processes is considered. The applicability of various numerical methods for determining the breakdown voltage is analyzed.
