초록

We fabricated thin film superconducting fault current limiters based on YBa$_2$Cu$_3$O$_{7}$ thin films and investigated the distribution of quench progress in the limiters. The limiters were tested with simulated fault currents. Quench progress depended significantly on the position in the limiter with respect to electrodes as well as the fault current magnitude. The heat transfer from limiter meander lines to electrodes explains these results.s.
