摘要：
Model study on the problem of high pressure oil filled termination failure due to the sudden loss of oil pressure on the energized line. Nitrogen saturated oil was found to have a very low internal breakdown strength under vacuum. Injection of Sulfur Hexafluoride (SF6) gas into the oil at low pressures prevented internal breakdown of the oil under vacuum. This study indicates that the injection of SF6 will help solve the termination failure problem. © 1990 IEEE
