Fault current limiter with novel arrangement of perfect YBCO loops made of HTS wire

In this work we examine a novel arrangement of a perfect closed superconducting loop made of HTS wire in a fault current limiter. This paper presents the results of our experiments with this device, which may open a new path for advanced applications by using continuous, perfectly closed superconducting YBCO loops. During the experiments we compared the fault current limitation in two arrangements. At the same time we also test the operation and application possibilities of the continuous YBCO loop developed by our own technology.
