Electrical properties of composite vegetable oils for insulation

This paper present the research on electrical properties of composite vegetable oils for insulation. The vegetable oils that are use are palm oil and corn oil. Test were carry out by applying high voltages ranging between 5 kV to 30 kV at room temperature 20 °C - 30 °C. AC breakdown test was used to analyze the breakdown voltage for the insulator whenever Dissipation Factor test was to determine the quality of the insulation. Beside, this paper investigate the resistivity and tan loss of the palm oil and corn oil whether those of vegetale oil are suitable to be insulation for transformer insulation oil or not. Beside that, this paper also make comparison for the charactheristic of the palm oil and corn oil. The caractheristic that are to be compare are breakdown voltage and tangent loss. To make comparison for this insulation oil, both of oil are mixed in a test vessel in different quantity or ratio in order to see the changes of the charactherictics of this vegetable oils. Other than that, the vegetable oil is good for cooking to health also has been determined in this study.
