Original Abstract

This paper deals with electrical discharge ignition in water solutions of selected electrolytes (NaCl, NaBr, and Na3PO4), and it describes particular processes before and after discharge breakdown by DC non-pulsed voltage up to 2 kV. Diaphragm configuration, with possibility to change the electrode distance (from 2 to 8 cm) and with different pin-hole diameters (0.3-0.6 mm), was used in experiments in order to estimate aninfluence of configuration parameters on the breakdown moment. The diaphragm was made of PET with its thickness of 0.25 mm. It was proved that the breakdown appeared at higher applied voltage when the electrode distance was enhanced. The influence of pin-hole diameter was less obvious in the studied range ,but a slight enhancement of breakdown voltage was observed with the increasing pin-hole diameter.
