“…POME processing using NaOH and KOH catalysts produced an alternative transformer insulation oil that meets several characteristics of insulation oil. Furthermore, to improve the insulation ability of the catalysed oil, a nanomaterial was added, namely, silica treated by saline, which can dissolve in oil [16,17,18,19]. The results of processing POME using a KOH catalyst with added silica treated by saline are better than processing using NaOH, which is also added silica treated by saline.…”

Various studies and research have been conducted to find alternatives to liquid insulation. One that is considered the most potential is vegetable oil since it has various advantages, including non-toxic, biodegradable, renewable waste products due to reactions in the form of CO2 and water, high flash points, and better thermal characteristics. In this study, Palm Oil Mill Effluent (POME) was used as the raw material for insulation oil with the addition of an additive in the form of nano-silica, which improves the quality of the insulation oil. As for determining the feasibility of insulation oil, characteristic tests were carried out in the form of density, viscosity, moisture content, acid number, pour point, flash point, and breakdown voltage. Based on the results of the tests, it was obtained that the lowest density in pure oil was 0.8757 g / cm³, the lowest viscosity in oil with the addition of 0.13 wt% nano-silica was 4.0248 cSt, and the lowest acid number in pure oil was 0.5797 mgKOH / g. It was also discovered that the pour point value is the same for each sample, the moisture content is 0.05%, the flashpoint is > 104 °C, and the breakdown voltage is ≥ 60 kV for each sample. The data show that the insulation oil made from POME has the potential to be used as an alternative to insulation oil.

“…This research seems to demonstrate the impact of area volumes on the dielectric properties of nanofluids derived from mineral oil. 19 In this research, a Two-Step Method (T-SM) can be described for preparing nanofluids by dispersion SiO 2 nanoparticle in base transformer oil at two distinct percentages. Researchers use coaxial electrode topologies in various tests to learn how area and volume affect nanofluids.…”

Transformer oil with a petroleum basis has long been used in transformers as insulation and cooling. The environmental concern of the current liquid insulating technique is how spent oil samples are disposed of after extensive use. Due to transformer oil's non-biodegradable composition, which can hurt and contaminate the environment, there is difficulty with disposal. A Nano Particle based Used Transformer Oil Processing Method (NP-UTOPM) is suggested in this research to reuse the used transformer oil in the battery. This work examines the effects of activated bentonite and carbon absorbents in recovering the qualities of used transformer oil by investigating the re-usage features of used transformer oil samples after reclamation treatment. 50ml of used transformer oil is utilized for the reclaiming process, along with separate mixtures of 1%, 3%, and 5%Nano Particles (NP) and blended combinations of two absorbents. According to international regulations, oil sample characteristics such as breakdown voltage, viscosity, dielectric dissipation factor, electrical conductivity, density, specific resistance, surface tension, and temperature properties are tested before and after restoration. The sample of recycled oil is used again as a liquid insulator in batteries.
