Transmission and distribution transformers are a critical part of the electricity generation and distribution network. The potential consequence of transformer failure can cause operation disruption and financial losses. In recent years, magnetic nanoparticles have been used to enhance the dielectric breakdown strength of transformer oil. Considering the inherent magnetic property of the magnetite...
A new class of colloidal dielectric fluids is formulated with the objective of enhancing the dielectric performance of mineral oil for application in power system. TiO2 nanoparticles modified by different organic reagents are suspended by means of sonication. Dielectric strength measurements are carried out under AC for a number of different colloidal systems with varying particle mass fraction. It...
Well-crystallized ZnO nanorods were prepared by a simple solution route using dodecyl benzene sulfonic acid sodium salt (DBS) as a modifying agent. The crystal structure and morphology of the as-grown product were characterized by X-ray diffractometer (XRD), scanning electron microscopy (SEM) and high-resolution transmission electron microscopy (HRTEM). It was found that the hexagonal ZnO nanorods...
