| Popis: | A glass insulation, coated with superhydrophobic soot and provided with two suspended electrodes, was made. An insulating cover is used to minimize the ejection voltage outside the insulation of any moisture and thus inhibiting its electrical flashover. It result that a covered deposit of drops under zigzag arrangement is expelled according to a groupo-individual and bidirectional evacuation mode under a voltage equal to 26% of that of insulation's flashover in dry case. This decreases with their volume whatever the distribution of their size and their conductivity. Under such a level of voltage, its longevity is largely optimized. |
