| Popis: | We present the comparison between the performance of an inductive superconducting fault current limiter operating with bulk Bi1.8 Pb0.26Sr2Ca2Cu3O 10+x rings or Y1Ba2Cu3O7-delta thin-film washers as secondaries. We have measured the impedance offered by the limiter under current faults and the recovery time once the faults are cleared. Our results show that the use of thin films can improve the impedance response of these devices and especially their recovery time, which can be about two orders of magnitude shorter than that of bulk samples |
