AC breakdown analysis of synthesized nanofluids for oil-filled transformer insulation

This work presents the effect of nanoparticles (Al2O3 and TiO2) on methyl ester synthesized from palm kernel oil for oil-filled power equipment. It investigates loss tangent, AC conductivity, breakdown strength ester-based nanofluid. The surface was functionalized with oleic acid before dispersing it into to modify stability mixture. Scanning electron microscopy coupled dispersive X-ray done two know morphology elemental composition nanoparticles. preparation nanofluids achieved through dispersion 0.2, 0.4, 0.6, 0.8, 1wt% ester. observed that loading reduces tangent conductivity but a pronounced enhancement in Al2O3 Weibull statistical analysis data shows base fluid increases characteristic an optimum performance at 0.6 wt%. TiO2 nanofluid is 60.6 kV 64.1 kV, respectively. result revealed possesses highest dielectric properties low loss, high which makes better replacement mineral insulating oil.
