Research Abstract

The present paper is aimed at investigating experimentally the interaction between the processes taking place in the stressed gas volume of a positivety stressed point-to-plane gap and those occurring at the walls of a surrounding dielectric enclosure. The corona current-voltage characteristics and the corona current density distribution over the ground plane are investigated
in the present paper with and without the presence of the dielectric enclosure. First of all, charging of the dielectric surfaces will be briefly reviewed. Secondly, the experimental setup is described. Finally, the obtained experimental results are discussed in the tight of gasdischarge
physics.
