摘要：In this paper, magnetite (Fe3O4) nanoparticles based nanofluid has been synthesizedand characterized for application in oil filled transformers. The intent of this work is to checkthe feasibility of magnetite based nanofluid through appropriate characterizations. Magnetitenanoparticles have been synthesized by chemical co-precipitation method and thecorresponding nanoparticles have been characterized by Raman spectroscopy, X-Raydiffraction, UV-Vis spectroscopy and Scanning Electron Microscopy. Further, ferrofluid hasbeen characterized at different concentrations of nanoparticles those including 10%, 20%,30%, and 40% w/v % to report optimal concentration for improved dielectric and thermalperformance of the nanofluid. Electrical measurements such as resistivity, permittivity andloss tangent at different concentrations of magnetite are reported. It is inferred that 20%concentration of magnetite is an optimal concentration with an improvement of 34% of BDV.Importantly, with the application of magnetite nanoparticles overall thermal and dielectricbehavior of the insulation fluid will be improved while reducing the size and weight of thetransformers.
