Dielectric properties of biodegradable vegetable oil based nanofluid

Oil fluids are commonly used materials in most nowadays transformers not just as dielectric materials, but also as the heat conductor for transferring heat from coils. This paper aims to show what possible effects could nanoparticles have in vegetable oil-based electro-insulating fluid, commercially called ENVITRAFOL. This paper presents the electrical properties of this material based on rapeseed oil and it's comparison with the same material modified by Al₂O₃ nanoparticles with a different value of wt.%. The goal of this research is to find suitable electro- insulating materials for transformers used in environmentally sensitive areas with biodegradable properties.
