This paper reports the electrical behaviors of atmospheric pressure plasma reactor with Dielectric Barrier Discharge (DBD) in air medium. The DBD discharge was generated in air at atmospheric pressure using Disc Electrode Geometry (DEG) reactor powered by ac voltage (0-7kV) at a frequency of 24kHz. The glass plates of thickness 1.0mm and 3.0mm were used as dielectric. The current-voltage characteristics were studied for two air gap of 2.0mm and 3.0mm by varying the applied voltages. The numbers of filamentary micro discharges were found as increased in each half cycle with increase in power. The observations of Lissajous figure of applied voltage versus electric current was used for measuring energy deposited by discharge and also compared with calculated value. Lissajous figures clearly show that the energy deposited by discharge was dependent on applied voltage. The electron density of discharge was measured by power balance method. Electron density was found in the order of 1017 per cubic meter.

Pressure Glow Discharge

In this report, an atmospheric pressure glow discharge (APGD) in argon has been invest igated by means of electrical measurement using parallel plate electrodes. The discharge was produced by passing argon gas at controlled f low rate of 1 lit/min, with dielectric barrier of glass between the electrodes. The inter -electrode spacing was varied from 1 mm to 3 mm. The electrical measurement of the discharge showed that there exists only one current pulse per half cycle in the current waveform indicating the formation of glow discharge. Power balance method was applied for the determinat ion of electron density. Our results showed that the electron density in the discharge is of the order of 1010 cm−3 with 26 kHz frequency of high voltage power supply.
