| Abstract | High Temperature Superconducting (HTS) materials bring to transformers benefits such as weight reduction and improvements in efficiency as well as the electrical behavior in the network. In the context of a European project (READY) we designed and built a 41 kVA single phase transformer that will use the first lengths of YBCO coated conductors for the secondary winding. Project partners are developing this conductor. The primary winding uses a PIT-Bi-2223 tape and we designed the transformer as a complete device with integrated cooling. The refrigerator is a large cooling capacity (100 W at 80 K) single stage coaxial pulse tube cooler developed by Air Liquide. We chose a cold magnetic circuit with low iron loss laminations. The cryostat is then very simple with metallic vessels and only one interface with the refrigerator. The cooling fluid is helium in order to investigate a large temperature range (40-80 K). Thermal simulations were made to minimize heat transfers to the HTS conductors and experiments provided some necessary data. The transformer design and optimization is presented as well as its construction. |

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.
