Abstract

This study aims to identify the effect of changes in temperature, water content, and
electrode gap on the breakdown voltage of transformer oil. The transformer oil used in this study
was Shell Diala-B and Nynas oil. Testing the effect of temperature was carried out at
temperature variation of 280 C to 810 C, the effect of water content was carried out with
variations ranging from 11 ppm to 31 ppm, and the effect of electrode gap was carried out in
variation ranges between 1.2 mm to 2.5 mm. Breakdown voltage testing method uses
hemispherical electrodes according to IEC 60156 standard of 1995. The results of the study
show that the higher the temperature, the higher the breakdown voltage of transformer oil. The
highest breakdown voltage in Nynas oil occurs when the temperature is 810 C which is equal to
59.27 kV. The results also show that the higher the water content, the breakdown voltage is
lower. The highest breakdown voltage in Shell Diala-B oil occurs with a water content of 11 ppm
which is equal to 61.35 kV. Also the greater the electrode gap, the greater the breakdown
voltage. The highest breakdown voltage in Nynas oil occurs with the gap of electrode 2.5 mm
which is equal to 60.02 kV.
