| Abstract | To introduce Superconducting Fault Current Limiters (SCFCL's) in a power system, some specifications such as the impedance, the trigger current level, the recovery time and so on are requested. Fault analyses point out that the accuracy of the trigger current level is required in several percents. Therefore, an SCFCL with adjustable trigger current level was proposed, designed and made. Adjustability of the trigger current level was confirmed experimentally. In addition, the SCFCL has good limiting and recovery characteristics. The SCFCL can recover in several tens of msec. It suggests that the SCFCL can recover when the current becomes small enough. In this paper, experimental and theoretical studies on recovery current of the SCFCL are described. Recovery current of the SCFCL was measured and the current of the secondary coil at the recovery operation was calculated. The minimum propagating current of the superconducting wire was calculated and it was compared to the current of the secondary coil just after recovery. Then, it is confirmed that the recovery current of the SCFCL's of proposed type can be calculated at designing. |

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.
