RÉSUMÉ

Gliding arc discharges are the subject of renewed interest in applications to a variety of chemical reactions. A gliding arc is created by a weakly ionised gas flowing between two electrodes. The reacting gas introduced at the base blows the arc column upwards. In order to analyse gliding arc fluctuations in air, a multi-shot camera was designed with a very short exposure time. With a special device, we could correlated electrical fluctuations with spatial evolution of arc and specially with jumping of arc root on the cathode.
