Studies on the effects of Al2O3 and TiO2 Nano materials on Conduction Properties of Mineral oil and Natural Ester based fluid

摘要

In the recent years there has been growing focus to find alternative fluids for transformer application for better sustainability as well as better dielectric properties. Natural ester is one such strong alternative. There has been also growing attention on the application of nano particles for improving dielectric properties. In this paper the effect of temperature and voltage on conductivity of mineral oil and natural ester oil in the presence of TiO₂ and Al₂O₃ nano particles have been studied using polarization and depolarization currents.
