Description | Superconducting fault current limiters (SFCLs) are expected to be installed in the power system for fault current limitation and improvement of power system stability. Among various SFCLs, we have proposed the transformer-type SFCL that produces limiting reactance for smaller fault currents and, additionally, gives limiting resistance for larger fault currents. Therefore, the transformer-type SFCL shows better recovery performance than resistive-type SFCLs. In this paper, we fabricated two transformer-type SFCLs using different high-temperature superconducting wires [Bi-2223 (BSCCO) wire and GdBCO, which is a kind of rare-earth-barium-copper-oxide (REBCO) wire] for the secondary coils and compared their current limiting characteristics. They were designed under the condition that the specifications of the primary coils and their trigger current level are about the same, respectively. As a result of comparing their current limiting characteristics, the transformer-type SFCL using GdBCO wire for the secondary coil shows a larger limiting reactance and dissipates less energy. Therefore, the transformer-type SFCL using GdBCO wire for the secondary coil shows better recovery performance. |

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.
