Study of Thermally Accelerating Aged Varnish Treated Insulating Paper

바니쉬 함침에 따른 절연지의 가속 열 열화특성에 관한 연구

This paper describes moisture content, dielectric strength and dielectric properties of thermally accelerating aged insulating paper as varnish treatment. Kraft, nomex paper were impregnated with diluted varnish, varnish and solvent were diluted in the ratio of 40wt%, in vacuum condition, and then completely dried. To analysis of papers were influenced by varnish treatment, we applied thermal stress, and then measured moisture content, dielectric strength and relative permittivity, $tan{\delta}$ as varnish impregnated papers.
