| Abstract | Non-uniform distribution on an insulator has a great influence on the DC pollution flashover voltage. a lot of investigations have been carried out on the non-uniform pollution flashover performance of the porcelain and glass insulators, but the research on the composite insulators is still very few. In this paper, based on the artificial pollution tests carried on the DC composite insulator, the influence of non-uniform pollution distribution of the DC composite insulator on the flashover performance is analyzed, and the correction formula of the non-uniform pollution flashover voltage is proposed. The test results show that, the correction formula indicating the influence of non-uniform pollution distribution on the flashover voltage could be expressed as K=1-b×log(T/B). For the tested composite insulator, the factor b is 0.141~0.156, which is smaller than those of porcelain and glass insulators. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
