Original Abstract

This paper deals with electric discharges generated by audiofrequency high voltage (15-100 kHz) in NaCl solutions (conductivity of 500 microS/cm). A batch plasma reactor in the pin-hole configuration contained a ceramic dielectric barrier separating two planar stainless steel electrodes; barrier thickness of 0.6 mm, pin-hole diameter of 0.3 or 0.6 mm. Electrical measurements were employed in order to characterise energy dissipation during the discharge ignition. Lissajouse charts were evaluated for different discharge phases (electrolysis, bubble formation and discharge regular operation). Subsequently, discharge power was estimated from the charts and plotted as a function of applied frequency.
