摘要：

This paper presents a technique to estimate moisture content in XLPE cable insulation through frequency domain spectroscopy. Tan $\delta$ over the frequency range 0.2 mHz to 110 Hz is correlated with moisture in the samples. The Havriliak-Negami (H-N) model is applied to investigate the changes in relaxation characteristics due to moisture and the moisture content is estimated through the correlation, which is used to cross validate the results. The comparative study shows that the estimated moisture content through the H-N model provides better accuracy than using tan $\delta$.
