Abstract
The fluorescence and optical transmission spectra of mixtures of dielectric liquids (petroleum oils and natural ester transformer fluid) were measured in the process of their artificial thermal aging both in the presence of insulating paper and without it. Approximations of the spectra of each of the components of the mixtures are performed. The real spectral characteristics are compared with the calculated dependences. Based on the experimental data obtained, it is shown that dielectric fluids have a mutual influence on both the aging process and the optical characteristics of the mixtures. It is established that the strong mutual influence of dielectric liquids was observed with artificial aging mix oil brands GK TC and natural ester MIDEL eN. The change in the optical characteristics of the mixtures during artificial aging is compared with the change in electrical resistance.
