要約(英語): When a stroke of lightning happens in the vicinity of the outdoor high voltage distribution lines, the inductive lightning surge invades to the central line of aerial insulated cables. The creeping discharges can progress along the cable surface from the free end of the binding wire just after the flashover of the insulator at the cable supporting points. If the weak points such as the pin-holes exist in the insulated coating near the cable supporting points, the creeping discharges may give rise to a punch-through breakdown of the insulated coating and melting or snapping accidents of the cable. To prevent these disasters, it is important to clarify the mechanism of the creeping discharge phenomena along the cable surface. The negative creeping discharge along the cable surface depends on the peak value of surge voltage and its progressing process is extremely complicated. We already reported photographically the progressing aspect of the negative creeping discharge using a high-speed image converter camera. In this paper, we consider the progressing mechanism of negative creeping discharge using the discharge models which propose on the basis of the discharge photographs that have been obtained by experimental observations.
