“…The electrical performance of high voltage porcelain and composite insulator strings under icing conditions was studied by Khalifa and Morris [67]. Under various atmospheric conditions simulated in the laboratory, the influence of ice density and conductivity on the flashover voltage of ice covered insulators was investigated.…”

“…En particulier, il a été démontré que la tension de tenue maximale des isolateurs dépend de la densité de la glace accumulée [1], [44], [45]. [36], [45], [48]- [50] soit par l'utilisation d'un cylindre témoin fixe ou tournant [30]- [33], [43], [46], [47].…”

“…Des études ont montré que les petits angles de déviation (<10°) n'ont pas d'effets notables sur la tension de contournement [4], [54]. Cependant lorsque l'angle de déviation est augmenté au- [42], [44], [62], [63]. En effet, dans le cas d'un isolateur de distance entre jupes faible, les glaçons vont combler l'espace entre deux jupes adjacentes plus rapidement, entraînant la formation d'un pont de glace.…”

“…Khalifa et al [77] studied the influence of atmospheric ice accretion on the performance of a high voltage insulator string in 1965. The critical leakage current of an ice-covered insulator was found to be less than the critical leakage current of a polluted insulator.…”
