Abstract
Transformer oil-based Nano-fluids with nanoparticles suspensions have substantially positive or negative voltage levels with respect to inclusion types and their concentrations in pure transformer oil. This paper has been studied the effects of powder nanoparticles for enhancing electrical and physical properties of pure transformer oils. Also, it has been dispersed low concentrations of Nano-sized Zinc oxide spherical particles in Diala D insulating oil for enhancing their physical and dielectric properties. Therefore, this paper presents performance of transformer oil nanofluids as alternative pure oil insulation for enhancing power transformer characterization and verifying the experimental results of dielectric strength and electrical properties of dielectric oil nanofluids medium based on nanotechnology techniques.
