Abstract | In order to solve the operation problems of traditional lightning protection equipment (for example, line arrester and parallel gap) for 220 kV AC transmission line, a novel lightning protection equipment – lightning flashover limited equipment for 220 kV AC transmission line – has been developed successfully, which owns the advantages of line arrester and parallel gap. Technical parameters, and electrical and mechanical performances are researched through theoretical calculation and experimental verification, and an installation structure of new split type is designed. The results show that the lightning flashover limited equipment has good electrical and mechanical performance and meets insulation, tensile, and bending requirements. By now, more than 200 sets of lightning flashover limited equipment for 220 kV AC transmission line have been applied on lines in four provinces of China. About 2 years of operating experience show that all the sets of lightning flashover limited equipment work safely and reliably. |

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.
