Abstract: On transition from the superconducting state to the normal conducting state, current limiters having a high-temperature superconductor increase their electrical resistance and thereby limit an electric current which is flowing through them. To provide electrical stabilization, the high-temperature superconductor is combined with a silver foil having a layer thickness of <50 &mgr;m to form an extensive composite conductor with good conductivity. The ratio of the layer thickness of the high-temperature superconductor to that of the silver foil should be >10. To produce this composite conductor, the silver sheet is placed on one side on a 2 mm thick MgO powder layer and, on the other side, is covered with a 600 &mgr;m thick so-called green sheet which contains a high-temperature superconductor powder and an organic binder.
