Abstract
A device, comprising a system of rod-plane electrodes with a horizontal axis, enveloping tubular glass barriers or vertical planes as well as supports for their attachment, has been made. The tubular barriers were coated with a thin layer of either superhydrophobic soot or hydrophobic silicone. The electrical performance of the tubular soot barrier has been determined experimentally based on its size and the length of the interelectrode air gap under DC voltage and any atmosphere. Its insulating performance was then compared with that of its tubular glass or silicone counterpart as well as that of the hydrophilic glass plane barrier under the above conditions. The main results obtained show, on the one hand, that under severe pollution conditions, the electrical protection of the rod-plane system by tubular soot barrier is more reliable than that of glass or silicone regardless of the influence’s parameters considered in this investigation. On the other hand, the tubular barrier with superhydrophobic soot is technically more efficient and economically less expensive compared to its hydrophilic plane counterpart.
