Abstract

This paper is written to show comparison between the naphthenic mineral oil with namely olive oil and sunflower oil in the context of voltage breakdown as insulating transformer oil. Olive oil is known to have been tested as alternative oil for transformer insulation and sunflower oil is a new oil being tested in this paper. The oils are mixed within certain ratios in order to determine the withstand breakdown voltages. The relationship of the breakdown voltages are also tied with the viscosity of the mixtures, and the mixture of oils are also exposed to ageing test and of tan-delta balancing test. All test follow IEC60156 standard test procedure for liquid insulation test. The mixtures were compared to the existing mineral oils and the findings will be discussed.
