The influence of a solid dielectric barrier on development of an electrical discharge in air between needle and plane electrodes is analyzed by means of computer simulations. The computational model describing formation and propagation of a streamer in atmospheric air and accounting for charge transport and trapping on barrier surfaces is presented. The results of the simulations performed for 5 cm...
We have clarified that the primary and secondary streamers have a significant impact on breakdown mechanism in air. In this paper, we focused on the highly-conductive channel progress breakdown, and considered the initiation condition of highly-conductive channel from the viewpoint of the secondary streamer initiation. We revealed that the highly-conductive channel initiation voltage in the case with...
Atmospheric pressure helium plasma inside a dielectric capillary and in the plume may exhibit stable and fascinating helix patterns. Such plasma propagation mode is achieved over an extended range of pulse repetition and gas flow rates. A key role of electric field is inferred from voltage, and electromagnetic configuration perturbation impacts on the plasma pattern. Helical plasma propagation is...
The measurement system detecting ns discharge current pulse during partial discharge (PD) was constructed to study the effect of the variation of needle curvature and aluminum foil diameter on the discharge parameters. Five types of needle electrode (with the curvature radius of 0.19 mm, 0.40 mm, 0.59 mm, 0.78 mm, 0.98 mm, 1.45 mm) and three types of round aluminum (with the diameter of 5 mm, 8 mm,...
