ABSTRACT:
A fault current limiter according to the invention comprises a contact device (K) to the contacts of which is connected a resistor/inductor combination comprising a series connection of a first (R1) and a second (R2) resistor as well as a third resistor/inductor (R3) connected in parallel with the series-connected resistors. The second resistor consists of a resistor with superconducting properties, dimensioned such that the change from superconducting to normally-conducting state occurs when the critical current density of the resistor is attained.
