| Popis: | In this study, a superhydrophobic insulation and a suitable electrode profile are developed to eject the water drops outside surface, with preventing any development of electrical discharges and/or the flashover of its surface under DC voltage. The effect of geometrical and electrical parameters of the water drops on its performance was quantified. Also, the evacuation of water drops using bridge-shaped electrodes without creating any electrical discharges is demonstrated. As well, the expulsion voltage is less than half of its flashover in dry case, and therefore, the superhydrophobicity of the insulation is better conserved and its longevity is optimized. |
