A fault current limiter is provided that comprises a fault current limiter comprising first, second and third magnetically saturable cores. The fault current limiter comprises a magnetic biasing arrangement arranged to produce a first magnetic circuit in the first magnetically saturable core, a second magnetic circuit in the second magnetically saturable core, and a third magnetic circuit in the third magnetically saturable core; first and second AC coils connected in series and connected to a first phase AC source, wherein the first AC coil is wound on a portion of the first magnetically saturable core and the second AC coil is wound on a portion of the third magnetically saturable core; third and fourth AC coils connected in series and connected to a second phase AC source, wherein the third AC coil is wound on a portion of the first magnetically saturable core and the fourth AC coil is wound on a portion of the second magnetically saturable core; and fifth and sixth AC coils connected in series and connected to a third phase AC source, wherein the fifth AC coil is wound on a portion of the second magnetically saturable core and the sixth AC coil is wound on a portion of the third magnetically saturable core. |
