  • Patent number: 7760067
    Abstract: According to a first aspect the present invention relates to a fault current limiter formed by a conductor tape (11, 41, 51, 61, 71) coated with a high temperature superconductor and having at least one mounting element (12, 42, 52, 62, 72) which is essentially holding the conductor tape solely on one or more edge regions in such a way that the principal surfaces of the tape cannot get in touch with the mounting element. According to a second aspect the present invention relates to a fault current limiter formed by a conductor tape coated with a high temperature superconductor and comprising at least one mounting element (23, 24) which is contacting the conductor tape on one or on both major surfaces in an electrically conducting manner such that the conductor tape (21) in its normal conducting state is electrically shunted by the mounting element (23) in the contact region.
