“…Similar results are obtained when caprylic acid is combined with RBDPO. In 2021, Walvekar et al [182] investigated the flash point of palm oil methyl ester (POME), which resulted in a temperature of 175.5 °C compared to the MO at 146.5 °C. In general, POME has a high saturated fatty acid composition of 17 carbons, which results in a greater flash point [183], [184].…”

Alternative transformer oil has been investigated universally in past years. Different types of vegetable oil have been proposed and evaluated as replacements for conventional transformer oil (mineral oil) due to increasing exploitation and depleting petroleum reserves. In response to growing concern about global environmental and sustainable issues, this article discusses the suitability of palm oil (PO) and palm oil-based nanofluids (PO-N) as alternative transformer oils. A brief discussion of environmental concerns is provided in this paper, and the detailed properties of PO are thoroughly addressed. The electrical performance (alternating current breakdown voltage and lightning impulse breakdown voltage), physical behaviour (viscosity, flash point, and fire point), tan delta, and relative permittivity of PO and PO-N are also discussed in this paper. Based on reliable data and research, it has been proven that refined, bleached, deodorised palm oil (RBDPO) has been determined to be the most promising type of PO when compared to others. Furthermore, when CuO nanoparticles are added to RBDPO with the use of CTAB surfactant, the AC breakdown voltage increases by 173.42 % compared to RBDPO without CuO. However, there is still scope for further improvement in nanofluid stability. In addition to these studies, future research should focus on other aspects such as ageing studies, partial discharge breakdown voltage, etc. PO has interesting properties that make the industry and scientific community take notice.

“…The conversion of triglycerides to methyl ester appeared to be the primary cause of the viscosity reduction. Low viscosity transformer oils are preferred because they promote heat transfer and circulation (Mohd et al, 2021;Walvekar et al, 2022). NPs employed increased, the water content of their NF decreased.…”

Numerous studies have been conducted on enhancing the dielectric properties of palm oil (PO) with the addition of nanoparticles (NPs). However, insufficient emphasis was given to its physicochemical properties, which are also critical for the function of an insulating liquid. The high viscosity of PO is one of the key factors which deteriorates the usage of natural ester in general, and PO in our case. This study was intended to investigate the performance of chemically modified PO by adopting a sequential transesterification process -NPs addition. The present work explored the transesterified PO blended with insulative (SiO 2 ) and semiconductive (ZnO) NPs at various concentrations (0.1-0.6 g L -1 ). The modified oils' dielectric strength and physicochemical properties (density, kinematic viscosity, and water content) were measured using standard testing methods. The results showed that the transesterification process effectively reduced the viscosity of PO, and adding ZnO NPs substantially impacted the PO in terms of AC breakdown voltage, with an optimum performance at 0.2 g L -1 concentration of 85% improvement. In contrast, while using SiO 2 , its breakdown voltage decreased irrespective of the concentration.
