| Abstract | Ever since it was demonstrated that installed extruded dielectric underground distribution cables lose significant dielectric strength due to formation of electrochemical trees in the insulation users have sought a means to determine the remaining useful service life. Subjecting miniature and full size crosslinked polyethylene (XLPE) insulated cables to accelerated aging tests and comparing the results to aging of I5kV cables removed from service the authors show how the remaining service life of installed cables can be estimated from dissipation factor measurements. This non-destructive test is made utilizing the available system voltage and would require the cable to be disconnected only several hours from service. The method devised to estimate service life is applicable to both polyethylene (PE) and XLPE insulated cables and its accuracy will be increased as more dissipation factor data is taken on cables now in service. |

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.
