Abstract

In order to investigate the electrical properties of naphthanic transformer oils for insulating and cooling, the characteristics for breakdown in temperature range of $20{\sim}100[^{\circ}C]$, that of AC breakdown in 1.0[mm] of gap length were made researches. As a result the characteristics for AC breakdown, it is confirm that the dielectric strength was increased to 6[ppm], 9[ppm] but decreased to 3[ppm].
