| Abstract | The use of a filler material in epoxy composite materials is an essential condition for reducing the unit cost of production and reinforcing the mechanical strength. However, the dielectric strength of insulators decreases rapidly due to interactions between the epoxy resin and filler particles. In contrast to existing composite materials, nano-composite materials have superior dielectric strength, mechanical strength and enduring chemical properties due to an increase in bond strength of the polymer and nano material. It has been reported that nano-fillers provide new characteristics different from properties of the polymer material. In this study, to improve the insulation capability of epoxy resin used in the insulation of a power transformer apparatus and many devices mold. To accomplish this, the addition amount of nano-SiO to epoxy resin was changed and the epoxy/SiO nano composite materials were made, and the fundamental electrical properties of them were investigated using a physical properties and analysis breakdown test. Using allowable breakdown probability, the optimum breakdown strength for designing electrical apparatus was determined. As the result, it was found out that the electrical characteristics of the nano-SiO content specimens were superior to the virgin specimens. The 0.4 [wt%] specimens showed the highest electrical properties among the specimens examined with an allowable breakdown probability of 20 %, which indicates stable breakdown strength in insulating machinery design. |

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.
