Institute of Experimental Physics SAS, Watsonova 47, Kosice 04001, Slovakia Correspondence: [email protected]: This assessment is focused on the analysis of dielectric fluids, specially usually Anti-Obesity Compound Library Protocol employed power transformer oils enhanced by nanoparticles, i.e., nanofluids. You can find variations amongst numerous combinations of base fluids and nanoparticles ready in distinctive methods. The key aim of this evaluation was to present current research in this field sorted by the used nanoparticles. Nanofluids based on mineral oils, organic, or synthetic esters have been investigated with regards to the nature of nanoparticles, especially Al2 O3 , TiO2 , Fe2 O3 , Fe3 O4 , graphene, fullerene, and other folks. The combinations of environmentally friendly oils and nanoparticles have been presented. Finally, the article focused on the description of current dielectric fluids usable in energy transformers plus the possibilities of enhancing new and existing fluids with nanoparticles, especially their physical, dielectric, and chemical properties, but with regard to environmental aspects.
