摘要: Theoretical investigation of the onset voltage negative corona on stranded conductors is described in this paper. The method calculation based criterion developed for formation repetitive Trichel pulses. This calls first an accurate electric field vicinity conductors. investigated gap a three-dimensional problem. To solve problem, new modification charge simulation technique presented, where charges are helical infinite length. Laboratory measurements carried out to check accuracy present calculations. effects varying nonuniformity values investigated. calculated agree satisfactorily with those measured experimentally.
