A fault current limiter apparatus 1 comprising a fault current limiter 10, including a magnetically saturable core, at least one AC coil wound on the core and a magnetic biasing arrangement for magnetically biasing at least one portion of the core; a source terminal 2 for connecting the apparatus to a power source and a load terminal 3 for connecting the apparatus to a load, where the coil of the fault current limiter is electrically connected between the terminals and where the fault current limiter has a first inductance in normal conditions and a second inductance in fault conditions. A first capacitance 5 is connected between the source and load terminals, where the first capacitance is connected in series with the fault current limiter and is arranged to have a reactance value that compensates for at least some of the first inductance. An alternate embodiment employing an overvoltage protection system in parallel with the capacitor is also disclosed. |
