Transformer oils used for the insulation and cooling of power transformer as insulating liquids is selected to study on the physical and electrical properties of insulating liquids. In order to investigate the electrical properties of transformer oils which contains a sodium chloride of 3[ppm], 6[ppm], 9[ppm], respectively, the dielectric and AC breakdown characteristics are made researches. Also, to study the physical properties of produced specimen, FTIR and /sup 1/H-NMR are investigated. |
