Dielectric characterisation of Fe(3)P nanoparticles based ester oil

Abstract

The insulation as the root source of failure and ageing assessor makes it a crucial point for any power equipment design. The transformer's insulation requires an efficient dielectric fluid that acts as an ideal electrical insulant and better thermal transporter. The objective of attaining that idealism in dielectric medium leads to the addition of solvents (i.e. additive and other fluids) in the conventional medium as one of its approach. This study presents addition of new magnetic nanoparticle iron phosphide (Fe(3)P) in insulating oil to achieve improved dielectric strength and withstand capability of the same conventional oil. A comparative study of nanofluids with different concentrations of nanofluids based on different insulating medium (i.e. synthetic ester and natural ester) has been performed. The concentration of additives and role of surfactant positively influences the dielectric characteristics of the base oil. The increase in breakdown strength is observed with a slight concentration of Fe(3)P nanoparticles added in the insulating medium.
