| Abstract | This paper reports on experimental investigations dealing with the influence of titanium dioxide nanoparticles on the breakdown voltage of transformer oil. $TiO_{2}$ particles with the nano size could be synthesized by the sol-microwave method. The materials characterized by XRD, SEM and TEM techniques. In this study, we have measured the dielectric breakdown voltage of transformer oil-based nanofluids in accordance with IEC 156 standard. The concentrations of $TiO_{2}$ nanoparticles in transformer oil are in the range from 0.001 g/l to 0.01 g/l. These concentrations for fresh oil (before and after the physical purification) and used oils for about 4 and 15 years, evaluated separately and the results were compared. Experiment results indicated that the addition of $TiO_{2}$ nanoparticles to transformer oil can enhance its dielectric strength and the surface compositions of the $TiO_{2}$ nanoparticles play an important role in its dielectric performance. When the volume concentration of nanoparticles is above 0.003 g/l, the dielectric breakdown voltage decreases. Based on test results and Due to the weather conditions in Gilan that has about 80 percent humid, titanium dioxide can be increase the breakdown voltage of transformer oils in free of moisture as well as humidity conditions. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
