Effect of Permittivity on Breakdown characteristic of Transformer oil based Nanofluid

Abstract

The expansion of forthcoming high voltage network and smart grid has upraised the desires on reliability and performance of insulating materials used in electrical power system to deal with more vigorous and volatile operating conditions. Since from long decades, in conjunction with paper the mineral oil or synthetic oil is mainly being applied as an insulating medium in many of the high voltage apparatuses. Concomitant development of advanced new materials with high insulation and thermal gains will ensure a significant upgrade in the reliability of liquid power equipment and hence the electrical network. These novel specific desires have brought the challenges to the transformer manufacturing companies to design the transformers with enhanced electrical and thermal properties. The transformer oil modified by nanotechnology has the potential to switch mineral oil base products in the marketplace due to its superiority in function and definite insulating and thermal properties. This paper discusses on the influence of nanoparticle's permittivity over the electrical performance of transformer oil.
