| Abstract | $SF_{6}$ gas used widely as insulating component in electric power industry has excellent in insulation and arc extinguishing performance in gas-insulated switchgear. However, the concern about eco-friendly alternative gas is currently rising because $SF_{6}$ gas is one of the main greenhouse gases. In this paper, dry-air and composite-insulation (dry-air + epoxy) as the alternative technology for $SF_{6}$ gas insulation is studied. Under the gas pressure ranged from 0.1 to 0.6 MPa, the breakdown voltage of dry-air is measured in AC electric field. The data of composite-insulation are ac acquired by changing the thickness of epoxy used in each composite-insulation under the same condition. As a result, in case of dry-air, the gas pressure needs to be compressed as about 3 times as that of $SF_{6}$ to maintain the same dielectric strength. When the epoxy is applied by the thickness, the breakdown voltage of composite-insulation is increased by the side of dry-air. However, the difference by the thickness does not exist almost. |

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.
