Abstract | We analysed the characteristics of the single, double and triple lines-to-ground fault of matrix type SFCLs (MFCL) with reactors for magnetic field. We compared characteristics of our MFCLs with those of resistive type SFCLs without reactors under the same experimental conditions. The magnitude of a limited fault current of MFCLs with a reactor according to fault voltages showed similar patterns directly after a fault. Also, the current limiting characteristics of MFCLs according to turn numbers of reactors showed similar patterns directly after a fault. However, the limitation of fault currents after 3 cycles showed a tendency to increase with increasing applying voltages. Our MFCLs had balanced patterns of limited currents between the R, S, and T phases. However unbalanced patterns of limited currents were observed in case of resistive-type SFCLs. It was because of unbalanced quenches between superconducting elements in resistive-type SFCLs and each phase. We reported the experimental results in terms of the properties of quenches, patterns of limited currents and limited voltages in the R, S and T phase systems. |

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.
