| Abstract | SF6 is the most commonly used insulating gas in electrical systems. But In these days SF6 mixtures and alternative gas has been studied because of global warming. so although many studies have been carried out about binary gas mixtures with SF6, few studies were presented about breakdown characteristics of SF6/N2 mixtures. At present study the breakdown characteristics of SF6/N2 mixtures in Non-uniform field was performed. In this paper, breakdown experiment values and breakdown simulation values are compared. Streamer theory was used for predicting breakdown voltage. For accurate simulation field factor, this simulation apply E field utilization using cst program AC breakdown experiments in non-uniform field was performed to compare with the breakdown simulation values. The pressure range of gas mixtures was 0.4 MPa to 0.7 MPa. The rod-plane was used and mixture ratio is SF6 20% : N2 80%. The gap lengths is 10mm to 70mm. As pressure increase, this simulation value do not correspond to the experiment value. So this simulation apply to utilization factor using CST program In the result, it was observed that breakdown voltage increase as pressure and gap lengths increase. But with gap lengths increasing, the breakdown voltage is saturated. So simulation need surface roughness factor. |

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.
