This study examines the effect of adding a mixed filler of Cerium Oxide (CeO₂) and Silicon Dioxide (SiO₂) nanoparticles on the dielectric characteristics of corn oil as an environmentally friendly alternative transformer insulating oil. The CeO₂–SiO₂ nanoparticle mixture was prepared in a 1:1 ratio with concentrations of 0,05; 0,1; 0,15; and 0,2 wt%. The experimental procedures included dielectric dissipation factor (tan δ) measurements at three temperature conditions (25–29°C, 40°C, and 80°C), breakdown voltage tests, dielectric strength calculations, and flash point testing in accordance with IEC-60247, IEC-60156, and ASTM-D93 standards. The results show that the addition of nanoparticles reduced the tan δ values for all samples compared to pure corn oil, indicating lower dielectric losses. The highest breakdown voltage was recorded at 0.05 wt% with an average value of 42.59 kV, representing an increase of 109.7% relative to pure corn oil (20.31 kV). The maximum dielectric strength, 17.03 kV/mm, was also achieved at the same concentration. Flash point measurements confirmed that the samples remained within a safe operating range. Overall, the incorporation of CeO₂–SiO₂ nanoparticles at an optimum concentration significantly enhances the dielectric performance of corn oil, making it a potential candidate for eco-friendly transformer oil applications. Keywords: Corn Oil, Cerium Oxide, Silicon Dioxide, tan δ, Breakdown Voltage, Transformer Oil
