Plausible linear relation between particle size of ZnO nanoparticles suspended in transformer oil and its breakdown strength

Zinc oxide nanoparticles were tested for increasing the dielectric strength of transformer oils for high voltage applications, but the results of other comparable nanoparticles proved to be more technically feasible as the relation between increase in breakdown strength and nanoparticles concentration was significantly better. This paper discusses a theory that describes a plausible linear relation between the increase in breakdown strength of transformer oil to the particle size of ZnO nanoparticles in suspension with experimental results.
