“…The interaction between the constant voltage corona discharge and the solid dielectric barrier was considered in [10]. It was shown that the main role during the interaction between the barrier and the corona discharge is played by the surface charge deposited in the course of non self maintained and self maintained stages of the discharge on the solid In this work we consider the discharge processes at the pulsed voltage impact leading to the appearance of one of the forms of the corona discharge: the pulsed streamer corona [6].…”

Features of the breakdown of the air gap with a large diameter solid dielectric barrier with pulse voltage supply are considered. Usually the preliminary closure of the gap by streamers is necessary for the breakdown of gaps with a length of 5-500 cm; however, in the considered systems the closure is hampered by the large length of the path in air by passing the barrier. The results of this study make it possible to assume that at a large diameter of the barrier the streamer-leader transition occurs on both sides of the barrier, then the pair of leaders propagates along the barrier on its different sides to the closure at the edge of the barrier. The possibility of the streamer-leader transition at moderate voltages (50-400 kV) can be provided by the considerable charge value transferred through the streamer channels on the surface of the dielectric barrier. The accumulation of the considerable charge on the surface of the barrier is possible due to the formation of a pair of spots of the heteropolar surface charge, a kind of an electric capacity.

In this paper, the electrical characteristics of both the dielectric barrier corona discharge and the usual ac corona discharge have been studied in parallel with the ozone generation under the same operating conditions. Therefore, the corona discharges were formed inside two identical reactors in the form of a coaxial wire-to-cylinder with and without a dielectric barrier covering the inner surface of the cylinder. The two reactors have been fed by constant flow rates from the dry air and the oxygen gas independently at the atmospheric pressure and the room temperature, in parallel with applying a sinusoidal ac voltage to the electrodes of the reactors. The electric power consumed in forming the corona discharges and the waveform of the discharge current as well as the ozone concentration generated in the flowing gases through the reactors have been studied versus the peak of the ac voltage that was applied to the reactors. The current-voltage oscillograms showed that the sequence of the dielectric barrier corona discharge modes in both the dry air and the oxygen gas is the same as the sequence of the usual ac corona discharge modes in the same gases. With the increase of the peak value of the ac voltage applied to the dielectric barrier corona discharge reactor, the peak of the discharge current increases linearly while the value of the electric charge accumulated on the surface of the dielectric barrier increases in the form of a power function. The ozone concentration generated by the dielectric barrier corona discharges is approximately equal to the ozone concentration generated by the usual ac corona discharges in both the dry air and the oxygen gas under the same operating conditions.
