介质谱在含水量测试运用中的问题探讨

Discussion on the Problem of Dielectric Spectrum in Water Content Test

介质谱测量的绝缘评估方法越来越被业界所普遍接受,通过介质谱测量能够比工频测量值更早也更有效地发现被试品的异常老化与缺陷状态,介质谱与含水量的关系在什么状态下达到一个阀值,与套管绝缘的关系是怎样的,通过不同的曲线分析可得出结论.

The insulation evaluation method for dielectric spectrum measurement is more and more accepted by the industry.The dielectric spectrum measurement can find the abnormal aging and defect state of the test article earlier and more effectively than the power frequency measurement value.In what state to reach a threshold,what is the relationship with the insulation of the casing,and draw conclusions through different curve analysis.
