The ongoing demands for the extra high voltage boost the need for looking for improving the conventional insulating materials by various modification techniques. Transformer insulating oil-based nanofluids (NFs) is one of these techniques. The present work aims to investigate the dielectric performance of transformer oil-based nanofluids and their dependence on the type of nanoparticles. To achieve this, three types of nanoparticles namely Zinc Oxide( ZnO) as conductive nanoparticle, Titanium Oxide (TiO2) as semi conductive nanoparticle and Silicon Dioxide (SiO2) as dielectric nanoparticles have been suspended in mineral oil (MO) at various concentration levels and the dielectric performance was tested by performing experiments such as AC breakdown voltage test, relative permittivity and DC conductivity. Experimental findings reveal that the use of nanofluids technique could improve the efficiency of the dielectric performance of mineral oil. The nanoparticle type and concentration have critical effect on the dielectric performance of prepared samples. For breakdown voltage, it is manifested that, samples prepared with ZnO nanoparticles exhibited the highest percentage of improvement. While for relative permittivity, samples prepared with TiO2 nanoparticles at higher concentrations, showed the highest percentage of improvement. On the other hand, all samples showed higher values in conductivity comparing with bare mineral oil sample.
