Experimental Investigation on AC Breakdown Strength of Insulating Oils Using Fe-Cu Bimetallic Nanoparticles

Abstract

The purpose of this article is to investigate the enhancement of AC breakdown voltage (AC-BDV) of pure synthetic ester oil and mineral oil using Fe-Cu bimetallic nanoparticles (NPs) based nanofluids. Bi-metallic or hybrid nanoparticles has not been explored much and they have potential to improve the electrical properties of insulating oils. There is consensus among studies that the production process used for nanofluids and the ideal concentration of nanoparticles are the most important factors affecting how well they perform, particularly in regard to their electrical properties. An investigation of the effects of different concentrations of nanoparticle and the configuration of the electrodes (Sphere-Sphere) and (Mushroom-Mushroom) have been performed, and their respective enhancements has been documented with the help of graphs. The possible cause of change in AC BDV has also been discussed. The maximum enhancement found in this experiment are 44.14% for synthetic ester oil and 54.32% for mineral oil in sphere electrode system.
