초록

In order to investigate the infulence of sodium chloride on the volume resistivity characteristics of transformer oils in temperature range of 20~100[$^{\circ}C$] were made researches. The geometrical capacitance of electrode with coaxial cylindrical shape for measuring the volume resistivity was 16[pF], and hoghmegaohm meter model VMG-1000 was used, the applying voltage were DC 100, 250, 500 and 1000[V]. The classification for the physical properties of specimen by FTIR Spectroscopy was carried out. AS a result of experiment, the value for volume resistivity is increased with sodium chloride contents.
