要約(英語): The partial discharge characteristics in Oil Filled (OF) cable were studied by using miniature model in order to clarify deterioration mechanism of OF cable with partial defects. It was found out that partial discharge may occur continuously when following three factors are caused together. One is the existence of the overlapped oil gap in the insulation papers of OF cable. The second is invasion of surge voltage superimposed on AC working voltage. The third is the reduced gas-absorption capacity of oil due to the large amount of dissolved gas in the oil. The paper covers the experimental results in the miniature model on the required conditions and development process of partial discharge in OF cables.
