Initial Results

This paper discusses on the breakdown voltage of vegetable oils with nanoparticles added to be used as insulating oil for transformers. Raw samples of Palm Oil (PO) and Coconut Oil (CO) were used in this research. Different percentages of silicone carbide (SiC) nanoparticles was added into the samples of the vegetable oils. The different parameters of the vegetable oil mixtures were investigated through the breakdown voltage tests to analyse the effect of the additive on the dielectric strength of the oils. The performance of insulating oils varies according to the percentage of nanoparticles added through viscosity test and partial discharge (PD) measurement. The initial results for vegetable oils showed that the percentage of additives influenced the value of breakdown voltage of the oils highly. Furthermore, the result shows that PD measured became very low after the addition of silicone carbide nanoparticles.

Insulation Oil

This paper presented the qualitative assessment of transformer insulating oil. The breakdown voltage, dielectric and acidity tests were electrically and chemically carried out on sixteen samples of transformer insulating oil collected from various serving distribution transformers in Ilorin Metropolis in Nigeria, through the supply authority. The adequacy of the obtained results was determined by comparing experimental values with America Society for Testing and British Standard (BTA4705) pre-requisites. About seventy five percent (75%) of the tested samples failed at least one of the tests, indicating inadequacy in the routine checks. Economic impacts of the obtained results and major causes and prevention of insulation oil degradation were also presented.

Insulation Condition

In general, transformer is one of the most important equipment in the power system, the reliability of a transformer is commonly determined by its insulation condition. The insulation liquid that has been used for decades is petroleum based mineral oil which has a very good cooling performance. However, it is insidious to the environment. Hence, vegetable oils such as coconut oil and palm oil are used as the alternative to replace the mineral oil. In this paper, it presents the comparative studies from previous experiments on dielectric strength, moisture content, viscosity, pour point and flash point of both vegetable oils.

Renewable Materials

Transformer oil insulation material is the result of processes from petroleum, the material that is not able to be renewed, increasingly scarce, expensive, an imported commodity, and the need is increasing. So it is necessary to strive for alternative transformer oil that comes from renewable materials, based on domestic production, increases the added value of a commodity and environmentally friendly. The alternative transformer oil in this case is coconut oil. For this reason, it is necessary to test the feasibility of coconut oil as an alternative to transformer oil which includes testing of physical, chemical and electrical properties. The test results are compared with the standard transformer oil according to the IEC. The test results, the flashpoint and dielectric strength are feasible as an alternative to transformer oil, the density, volume expansion coefficient and viscosity of coconut oil are not suitable for use as an alternative to power transformer insulation oil. The percentage in terms of physical properties is 25%, with 4 tests of 10 existing physical properties. The feasibility of electrical properties is 50% with 1 test of 2 existing electrical properties.

Due to concerns over the world’s energy necessity and environmental impact of mineral oil, these conditions induce many researchers to search for substitute sources for insulating oil. Alternatives insulating oil with biodegradable characteristics, environment friendly and presented in different countries including Bangladesh such as vegetable oils have been proposed for high voltage applications. In this paper, a relative measurement of breakdown voltage through experimental investigation of coconut, mustard, soybean, and palm oil and their blend (which is available in Bangladesh and cost effective) is presented. Break down voltage was measure with different electrode configuration by changing gap distance. The results show that the blend of (50% coconut oil + 50% palm oil) got high breakdown voltage in mushroom-mushroom electrode, and other side in plane-plane type pure soybean oil got high breakdown voltage, compared with transformer oil. The presented result illustrate that the proposed mixed oil provides better performance than the rise husk oil.
