The conditions of formation of a corona discharge have been investigated. The discharge was as a dense plasma substance on a anode spearhead. The substance had considerable length. Solution NaCl in wa- ter as environment. The electrical conductivity of solution was more than 15 20 Om-1m-1. The speed of the extension of plasma has been determined. The initial electric field strength and specific power inputs for ero- sion of an anode has been counted. The estimation of a degree of density of a plasma volume has been con- ducted.
