Документ Разрушение поверхностного слоя диэлектрика в концевых кабельных муфтах под действием грозовых перенапряжений(НТУ "ХПИ", 2013) Гурин, Анатолий Григорьевич; Гонтарь, Юлия ГригорьевнаQuestions of destruction of a blanket of polymeric dielectric of a cable in trailer couplings under the influence of the full and cut-off impulses of a storm overstrain are considered. Impact of limiters of an overstrain on expansion of a range of high-frequency components in overstrain impulses that can lead to manifestation of “Vorobyev’s effect” when volt-second characteristics of superficial and volume breakdown are comparable is had and probability of overlapping of isolation is comparable with probability of breakdown. This process accelerates development water treeing and cracking of blanket of isolation.
