摘　　要：交联聚乙烯 (XL PE)电缆在我国的应用越来越广泛 ,其绝缘老化的在线检测也日益提到议事日程上来。论文就直流叠加法在线检测电缆老化进行了研究 ,用软件作仿真 ,并通过实验得出直流叠加法的切实可行性。With the development of cross linked polyethylene power cable, it is often discussed how to monitor it on line cleverly. In this paper, an on line diagnostic measurement system based on the DC superposition method was described. By analyzing circuit and simulation test, it is proved DC superposition method is feasible.
