Generalizations of the experimental current-voltage characteristics of corona discharge for helium and the synthetic air at positive and negative polarities of the discharge electrode of a complex star-shaped form at different gas pressures are presented. Analogous generalizations are carried out for current-voltage characteristics obtained for the dried air and a coaxial system of electrodes at various temperatures and the atmospheric pressure. The generalization consists in reducing the family of current-voltage characteristics to a single generalized equation which geometrically represents a segment bisector. Some aspects of application of similarity methods at corona discharge are considered. Townsend’s structure of characteristics is confirmed and this fact can serve as a prerequisite for its wide application.
Keywords: corona discharge, current-voltage characteristics, helium, air, generalization, similarity criteria.
