| Abstract | Polymeric materials like mineral filled and fibre reinforced epoxy resins are used in many power apparatus for electric insulation. Compared to ceramic and glass the composite insulators based on mineral filled polymers have many advantages. Epoxies offer new possibilities in developing electric insulations, especially to reach more compact design in electric power equipment. Due to their good adaptability, their convenient manufacturing technology, their very good electric and mechanical properties, mineral filled epoxies are the preferred duromeric materials for many high quality insulating systems. These materials for outdoor and indoor use show ageing phenomena under environmental stress which is not exactly known up to now. For this reason it is important to get a reliable state of estimation with loss factor and partial discharge measurement. Mineral filled epoxy test specimens are aged by water immersion due to environmental stresses in outdoor applications. The loss factor, partial discharges (PD), the glass transition temperature, the electrical strength and mechanical properties are measured in selected time intervals. The measuring results and a theoretical explanation of ageing effects on electric and dielectric parameters are presented. |

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.
