Abstract In the field of transformer insulation diagnostics, to evaluate the insulation condition of a transformer, it is necessary to calculate the frequency domain spectroscopy of the oil-immersed paper with the structural parameters. However, as the transformer structure is often unknown in on-site measurement, the application of the frequency domain spectroscopy (FDS) method is greatly limited. This paper proposed a method to extract the frequency spectroscopy of the oil-immersed paper without the known transformer structure based on second-order gradient RMS. The frequency spectroscopy of the constructed oil-paper insulation with different moisture conditions and structures were measured and the frequency spectroscopy of the oil-immersed paper was calculated according to the structural parameters. As the research shows, the structural parameters deviated from the actual value influence the shape and size of the calculated frequency spectroscopy curve of oil-immersed paper, which significantly increase the second-order gradient RMS. The influence is less with higher moisture content. By traversing the structural parameters in the calculation of frequency spectroscopy of the oil-immersed paper, the structural parameters and frequency spectroscopy is analyzed based on the minimum second-order gradient RMS. Therefore, the frequency spectroscopy of the oil-immersed paper is extracted without the known transformer structure.

Key words： Transformer major insulation oil-paper insulation frequency domain spectroscopy (FDS) oil-immersed paper
