Features of a low-power, low-frequency, AC arc between solid and liquid electrodes

The results of an experimental study of an AC arc between solid and liquid electrodes at low frequencies and atmospheric pressure are presented. Arcing is established at a frequency of $33.3$ Hz. The oscillogram and the current-voltage characteristic in one half-period of an AC arc between a copper electrode and industrial water are given. The current-voltage characteristics of the arc discharge between plate metal electrodes and process water are presented.
