Exploring the Dielectric Strength Enhancement of Virgin Coconut Oil as an Alternative Transformer Liquid Insulation through Nanomaterial Additives
Virgin coconut oil (VCO) is a biodegradable natural ester whose dielectric strength and thermal performance remain below those of mineral oil. This study enhanced VCO with surface-modified TiO₂, Al₂O₃ and SiO₂ nanoparticles (0.01–0.05% w/v), prepared by magnetic stirring and ultra-sonication and characterized by XRD, SEM/TEM, EDX, FTIR, UV–Vis and ...
