| Abstract | Tests were made on several types of air gaps in order to support the revision of IEC 60.1/1973, for studying the atmospheric correction parameters. To verify the new correction factors, several dielectric tests were done on station post glass insulators, with different atmospheric conditions. The results were corrected using the IEC 60.1/1973, the revision dated December of 1987, and the exponent curves suggested by A. Pigini et al. (1983) and plotted as disruptive voltage (U50%) versus the ratio between the absolute humidity and relative air density (H/RAD). The graphics obtained can be used to verify whether the correction factors are properly dimensioned. When it occurs, the straight line obtained by the application of linear regression must be parallel to the axis of H/RAD variation (that is to say, the value of the inclination is equal to zero) and the range of U0 (the value of U50% when H/RAD is equal to 11 g/m/sup 3/) must have the smallest width possible. |

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.
