The manuscript presents experimental research, plasma reactor with two mesh electrodes and a micanite dielectric. Three types of electrode geometry were used in experimental research; mesh size 0.1x0.1mm, 0.3x0.3mm and perforated electrodes with holes Ø1.38mm. The results of experimental research show the influence of electrode geometry on the ozone generation process. The use of electrodes perforated with Ø1.38mm holes generates 20% lower ozone concentration, compared to configuration with two mesh electrodes size 0.1x0.1mm at the same discharges power.
