摘　　要：针对传统的多频介电响应测量方法的弊端,提出了新型的多频介电响应测量方法。将该多频介电响应测量方法用于测量输电线路中电缆的绝缘性能,发现电缆老化时间越长,其介电损耗正切值越大,且频率谱线越高。In view of the drawbacks of traditional multi-frequency dielectric response measurement methods,a new multi-frequency dielectric response measurement method is proposed in this paper.This multi-frequency dielectric response measurement method is used to measure the insulation performance of cables in transmission lines.It is found that the longer the cable aging time,the larger the tangent value of dielectric loss and the higher the frequency spectrum.
