The thermal aging of insulating fluids and papers in composition of paper-impregnated insulation was investigated. Electrical and optical characteristics of the mixture of petroleum oil and synthetic ester are studied. The mechanical and electrical properties of the paper before and after aging were measured. The sorption capacity of some types of cellulose paper was evaluated. The significant dependence...
The thermal aging of insulating paper in composition of paper-impregnated insulation was investigated. The mechanical properties of the paper before and after aging, as well as other parameters were measured, in particular, the tangent of dielectric loss angle and the relative light transmission transformer oil. The sorption capacity of some pulp and dielectrics was evaluated. The significant dependence...
In the work were investigated optical, electrical and mechanical properties and heat stability of the components of paper-impregnated insulation of power transformers. It is established that Increase of sorption activity of cellulosic material can slow process of destruction of the liquid dielectric due to retention of the products of aging of paper and oil The spectral transmission characteristics...
