| Abstract | We made a co-axial copper tube measurement device in order to measure AC losses of HTS tapes. This device can minimize the external disturbance for high accuracy measurement. Also it is easy to fix the tape inside the copper tube. We used a linear amplifier in order to measure the voltage in high accuracy because the transport current was large. The voltage taps are located at the center and the edge of the tapes to measure the voltage drop on the samples. Our experimental data show that the inductive voltages are proportional to the frequency, and therefore this means that the main loss depends on hysteresis loss. In this study, the AC loss characteristics of twisted Bi-2223 tapes and untwisted tapes carrying AC transport current in self field is investigated. The magnetic flux generated by the transport current flowing in the HTS tape can be measured by using the same experimental setup. If the superconducting filament is twisted to reduce the AC losses, a relatively higher magnetic flux is induced at low frequencies, this is measured by winding the measuring wire around the tape - winding pick up method. |

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.
