Abstract

This study examined the effects of the turn ratio and direction of two serially connected coils on the current-limiting performance of YBCO thin-film wires with different stabilization layers. Three YBCO thin-film wires with different stabilization layers were used to manufacture current-limiting elements, and their current-limiting performance was evaluated. The test equipment that consisted of two serially connected coils was connected to the current-limiting superconducting elements that were manufactured with YBCO thin-film wires. Finally, the current-limiting characteristic of each current-limiting element and its operation as a superconducting fault current limiter (SFCL) were examined after the turn ratio and direction of the two coils were varied. The current-limiting characteristic of the current-limiting element and its operation as a SFCL were verified the resistance generation tendency, current-limiting ratio, and response time as indicator.
