A fault current limiter comprising a first resistor layer (2) consisting of a material which may become superconducting and the second resistor layer (3) consisting of a normally conducting material one resistor layer being arranged on top of the other. The second resistor layer is dimensioned such that its resistance becomes considerably lower than the resistance of the superconductive layer in its non-superconducting state, however with a resistance of such a magnitude that, in the current circuit in question, limits the current to a permissible value. For mechanical support of the resistors, an insulator (1) is included in the current limiter, and the superconducting material or the normally conducting material, respectively, is immediately applied on said insulator. The resistors and the insulator are arranged immersed into a cryotank. |
