Influence of surface modified Fe3O4 nanoparticles on the dielectric properties of Natural ester based Nanofluid

Investigations during the last decade has shown that nanoparticles can be dispersed in insulating oils and form Nanofluids. There are promising results showing that the addition of nanoparticles to conventional transformer oils can improve their electrical and thermal characteristics. However, it is a challenge to surmount the problem of the agglomeration and expand the investigation to natural ester liquids apart from minerals. In this paper, a study on the dielectric properties of a Natural ester based oil Fr3TM with the addition of surface modified Fe3O4 nanoparticles is presented. Surface modification of the nanoparticles is a vital procedure to avoid nanoparticle agglomeration in insulating Nanofluids. Herein, the Fe3O4 nanoparticles, known as magnetite, were ultrasonic dispersed and…
