Very high currents can be induced in pairs of current-carrying superconducting rings when they are coaxially brought closer. If the currents are uniformly distributed through the cross-section of the rings their magnitude can be derived from the mutu

We report some of our experimental results about the transition to the normal state of high-temperature superconductors subjected to high current densities and, simultaneously, under external magnetic fields up to 1 T. Our data analysis, which is bas

Pairs of YBa2Cu3O 7 − δ rings, which behave as magnets due to persistent currents circulating through them, were coaxially confronted and the force between them has been measured at different distances. The constance of the magnetic flux through t

We first present detailed measurements of the rounding behavior around the superconducting transition temperature, $T_c$, of the in-plane electrical conductivity, magnetoconductivity and magnetization, including the low and moderate magnetic field re

Here, we study the behaviour of an inductive superconducting fault current limiter (SFCL) whose secondary is a bulk cylinder with an array of appropriately distributed weak zones. This design allows heat to be removed by conduction from the hot weak

Inductive fault current limiters operating with stacks of various small superconducting elements acting as secondaries were studied. The stacks consist of Y1Ba2Cu3O7?? thin film washers or Bi1.8Pb0.26Sr2Ca2Cu3O10+x bulk rings. A central result of our

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

We report results on the behaviour of an inductive fault current limiter prototype with weak zones artificially created. The superconducting elements are Bi-2223 rings and the tests have been realized with the device on a Helium gas environment at 77

We study here the limitation performance and the thermal recovery of inductive superconducting fault current limiters (SFCL) with special emphasis on the case in which the superconducting element (i.e. the secondary) has weak zones. Our experimental

In this work, we have studied the performance of an inductive fault current limiter having biphase (Bi-2223 and Bi-2212) superconducting rings as the secondaries of the transformer. We have paid special attention to the role played by the inhomogeneo
