| Abstract | A versatile, high-temperature superconducting (HTS) cable test facility has been designed and assembled at Oak Ridge National Laboratory (ORNL) in a joint program between ORNL and Southwire Company. The facility mission is to evaluate the performance of prototype HTS power transmission cables at lengths in the range of 1 to 5+ m. Power supplies are available for steady-state currents of 3000 A (DC) and 2000 A (AC) as well as up to 25000 A (DC) for pulsed loading. Cryogenic cooling is provided by an Air Products liquid nitrogen supply system with the capability of providing about a kilowatt of cooling at pressures up to 10 bar over a temperature range of about 67 to 77 K. Electrical and cryogenic data are taken by dedicated sensors scanned by ten-channel multimeters connected via cable and fiber optic to a personal-computer-based, data acquisition system using the LabVIEW program. These diagnostics allow measurement of the DC V-I characteristics and AC loss of the cable, dielectric integrity via a partial discharge measurement, and cryogenic performance at rated voltage (7.2-kV AC) and current (1250 A). Initial results from facility commissioning and early HTS cable testing are reported,. |

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.
