摘　　要：通过对其进行频域介电响应测试并对特征频段内的FDS进行积分运算提取到了能够定量表征绝缘受潮状态的特征参量;基于建立介损积分因数与绝缘受潮状态的函数关系并且消除温度对FDS的影响,实现了对绝缘含水量的定量评估。The frequency domain spectroscopy(FDS) test and the integration operation of FDS is performed, the characteristic parameters that can quantitatively characterize the moisture are extracted. Based on establishing the functional relationship between dielectric loss integral factor and moisture, as well as eliminating the influence of temperature on FDS, the quantitative evaluation of moisture content is realized.
