    In the present study, DC discharge propagation on an ice surface was photographed using a high-speed camera and the corresponding voltage and current waveforms were recorded. Due to the importance of the arc root, which supplies the required energy to the discharge column, the effect of the presence of multiple arcs on the propagation mechanism was investigated. It was observed that the propagation features for an arc with both ends on the ice surface differs from that with one end on the ice and the other on a metallic electrode. The effect of the presence of multiple arcs and position of air gaps were studied and compared with the propagation of a single arc with one root on the ice surface.
