Abstract As a potential substitute of mineral oil, silicone oil has been widely used in power equipment such as transformers. In order to study the influence of moisture on the frequency domain spectroscopy of silicone oil impregnated insulation paper, firstly, this paper proposed a method to separate conductance loss and polarization loss in the imaginary part of the complex permittivity by theoretical derivation, prepared silicone oil impregnated insulation paper samples with different moisture contents, and separated the conductivity loss and polarization loss in the test results and analyzed the influence of moisture on dielectric response process. The relationship between dielectric characteristic parameters and moisture content was extracted through the Havriliak-Negami model parameter identification. The results show that there are loss peaks in all polarization loss curves of silicone oil impregnated insulation paper, and as the moisture content increases, the frequency band of the loss peak gradually widens and moves toward the high frequency. The proposed method can significantly improve the data reconstruction accuracy of HN model. The functional relationship of the integral feature quantity S₁ and S₂, the dielectric relaxation strength and the moisture content can provide a reference for moisture evaluation of silicone oil impregnated insulation paper.

Key words： Silicone oil impregnated insulation paper moisture frequency domain spectroscopy separation of imaginary part of complex permittivity Havriliak-Negami model
