“…It was observed that the biggest IF WS 2 clusters get sedimented to the bottom during the first hours of preparation. Baharuddin et al [75] investigated the dispersion stability of surfactant-modified SiO 2 nanoparticles mixed in mineral oil by visual observation. The authors reported that the addition of surfactants reduces the agglomeration of the nanoparticles by reducing their surface activity.…”

With the advancement in the field of nanotechnology, various researchers have reported an improvement in the friction and wear behaviour of different lubricating oils by the addition of different nano additives. However, the stability of these nano additives remains a challenge. In this paper, the dispersion stability of various nano additives in lubricating oils has been studied in detail. The paper aims to summarize various dispersion stability theories and several methods reported in the literature to improve dispersion stability. Apart from this, a special focus has been laid to highlight the various surfactants used to improve the dispersion stability, particularly the tribological properties. The literature suggests that although a number of studies have been carried out to study the effect of surfactant addition on dispersion stability, however, future developments could be focused to improve the dispersion stability of the existing mono and hybrid nano fluids and their underlying mechanisms.Abbreviations: SWCNH, single-walled carbon nano-horns; PAO, poly alpha olefin; MoS 2 , molybdenum di sulphide; H

“…Baharuddin et al [99] examined different concentrations of surfactant (cetyltrimethylammonium bromide (CTAB)), which was added to the mixture of MO and Al 2 O 3 nanoparticles with a diameter of 13 nm and concentrations 0.1 wt% to 0.5 wt%. The maximum improvement showed the nanofluid with 0.1 wt% of Al 2 O 3 nanoparticles.…”

This review is focused on the research of dielectric fluids, especially commonly used power transformer oils enhanced by nanoparticles, i.e., nanofluids. There are differences between various combinations of base fluids and nanoparticles prepared in different ways. The main goal of this review was to present recent research in this field sorted by the used nanoparticles. Nanofluids based on mineral oils, natural, or synthetic esters were investigated in terms of the nature of nanoparticles, particularly Al2O3, TiO2, Fe2O3, Fe3O4, graphene, fullerene, and others. The combinations of environmentally friendly oils and nanoparticles were presented. Finally, the article focused on the description of current dielectric fluids usable in power transformers and the possibilities of improving new and existing fluids with nanoparticles, especially their physical, dielectric, and chemical properties, but with regard to environmental aspects.

“…The oil-filled transformer's insulation system is made up of organic materials, primarily hydrocarbon oil and cellulose insulation. The insulating oil serves primarily as a heat transmission fluid [1]. The cellulose insulation, which includes a pressboard and paper, provides mechanical support and separates the transformer winding.…”

The most crucial parts that decide the transformer’s lifetime are the solid insulation of the power transformer, especially the pressboard and kraft paper. The life of the insulation is significantly influenced by the presence of water in the insulation. This paper presents a study on partial discharge (PD) on the existing normal pressboard (NP) and the newly developed Kenaf-polypropylene pressboard (KPP). Also, the moisture content of the pressboard varied between 0%, 1%, and 3% by the percentage weight of different methods. After the initiation of PD, the surface deterioration analysis was performed by using scanning electron microscopy (SEM). The results from the study revealed that KPP shows superior performance in mitigating PD. At 0%, 1% and 3% moisture contents, KPP showed 89%, 83% and 25% reductions in average PD magnitude, respectively. Overall, the kenaf composite pressboard has better PD resistance, which is one of the things to think about when insulating a transformer.
