| Abstract | In the E.U. research programme ARTEMIS 90 kV cables insulated using the same batch of XLPE were stressed under different electro-thermal conditions for various durations. Thin peelings of the insulation of the cable sections stressed in this way are compared with peelings taken from an unstressed cable section, through their ac electro-thermal endurance measured under the same test conditions, to see whether or not the cable stressing had altered the inherent endurance capability of the insulation material i.e. aged it, and to identify markers for the dominating process/es that degraded the materials. Their space charge behaviour was also measured by the Pulse-Electro-Acoustic (PEA) technique before and after the endurance test, in order to characterise the material from the stressed cables and to identify changes brought about during the endurance test. The measurements focussed on the accumulation of space charge under a standard measuring condition of 50kV/mm at room temperature, and its subsequent decay. The results show that the ARTEMIS stressing as well as the endurance test introduced changes to the space charge behaviour. |

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.
