| Abstract | The electrical behavior (DC conductivity and AC properties) of XLPE (cross-linked polyethylene) cable models aged under thermal stress is investigated as a function of aging time. Charging and discharging currents as well as the dielectric constant and loss factor of specimens aged at different times and temperatures were measured from 55 to 90 degrees C and 10/sup -2/ to 10/sup 5/ Hz AC properties. Significant variations of DC conductivity and AC losses with aging time and temperature are pointed out. Cable models thermally aged above 100 degrees C revealed a strong increase of DC electrical conductivity with aging time. The same behavior, i.e., increase with aging time at 100 and 130 degrees C, is exhibited by dielectric constant and loss factor. The observed increase of electrical conductivity and dielectric losses supports the build-up of thermooxidative processes in thermally-aged specimens. |

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.
