| Abstract | For AC loss reduction on multi-layer superconducting cables, it is important to balance the current sharing ratio among layers by adjusting spiral pitch angles of wires. The effects of this technique were analyzed by using a conventional theoretical approach and a newly developed numerical approach. In the numerical analysis, three-dimensional FEM algorithm was modified to treat nonlinear superconducting properties, and complicated spiral pitch condition was simulated by introducing anisotropy on the conductivity of each layer's conductor. This numerical analysis made it possible to visually observe electromagnetic properties and current distribution within each superconducting layer. This analysis revealed that the theoretical approach without taking the superconducting properties into account does not provide an accurate solution of spiral pitch for balanced current sharing among layers. This result supports the importance of this kind of numerical approach for the analysis of superconductors. |

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.
