“…In conclusion, our experimental results confirm that cracking and hot spots are a major obstacle to the application of bulk HTSs to resistive SFCLs [17][18][19], being necessary to attach a protective shunt layer to the bulk HTS to avoid its cracking.…”

“…However, this SCFCL component requires a recovery time of several minutes, which makes it more suitable for application in bus-ties. Indeed, the 10 MVA SCFCL prototype built with MCP Bi-2212 bifilar coils was installed in a bus-tie of the German power network [4].…”

“…Resistive SCFCL components based on a bulk (Bi-2212) bifilar coil were developed by NEXANS SuperConductors [9]. Such Bi-2212 components were used in a 10 kV/10 MVA SCFCL prototype, which was successfully demonstrated [4]. These bulk coils are shunted with a Cu-Ni alloy which is continuously soldered over the whole superconductor length (5.4 m) [9].…”

A shunted bulk Bi-2212 bifilar coil was cooled with liquid nitrogen (77 K) and subjected to controlled fault current tests. Prospective currents achieving 11 kA were limited to about 5 kA (first peak) and to 3 kA (following peaks), under 200-300 V. The Bi-2212 coil was able to withstand several short circuits, showing a fast response and reproducible results. A recovery time of minutes was needed between two successive tests. Therefore, the bulk coil was damaged when the interval between subsequent short-circuits was reduced to 30-60 seconds. The critical current was severely reduced by those last tests and further thermal shock. The bulk coil was cut in transversal and longitudinal sections, in order to evaluate the damages.

“…And, if fault current flows, superconducting element is quenched, within 1/4 cycle fault current is limited. It minimizes the influence to the external equipment in electric power system and minimizes the damage, as well as after completing the fault current limitation role, within 0.5 sec it is reversed to superconducting status [3][4][5][6][7].…”

-At present, the demand for electric power increases, the electric power system is complicated. The size of the line-to-ground fault and the line-to-line fault occurred with complication of electric power system continue to increase, therefore several issues are raised. To address these issues effectively, the superconducting fault current limiter (SFCL) has been proposed, this study is ongoing. In this paper, we applied the SFCL in three-phase transformer and comparative analysis of the electric power burden to the SFCL. The superconductor is combined to the third winding of transformers in connection structure. In case of a third line-to-line fault, we did comparative analysis of the electric power burden to the SFCL based on the turn ratio of transformer third winding. In this case, we could confirm as the third turn ratio increased, electric power impressed to the superconducting element increased.
