Abstract
– The research on CPO as an insulator to replace mineral oil. The CPO was heated using vacuum distillation technology. The parameters used are the temperature of 110°C to 170°C with the difference of 10°C and the vacuum pressure of 0 mmHg to-600 mmHg with the difference of 200 mmHg. The highest breakdown voltage measurement of 49 kV (170°C-600 mmHg), the lowest viscosity is 20 mPas (170°C-600 mmHg), the lowest water content was obtained at 30 (160°C-400 mmHg). The vacuum pressure and temperature rise causes the high breakdown voltage and viscosity are high and the water content is low. The relationship between vacuum pressure and breakdown voltage is y = 5.8 x + 7 with R2 of 0.9397, the viscosity is y = -2x + 35.67 with R2 of 0.9231 and the water content is y=-7.25x2 + 22.95x + 106.75 with R2 of 0.9945.
