Fault current limiter

A fault current limiter comprising:

• first and second ring cores, wherein each of the first and second ring cores are separated into ring core segments by a first plurality of air gaps;
• and
• a series of permanent magnets sandwiched between the first and second ring cores, wherein the series of permanent magnets are punctuated by air gaps,
• wherein a second plurality of air gaps are respectively positioned between each of the permanent magnets in the series of permanent magnets, and
• further wherein a third plurality of air gaps extend through each of the permanent magnets to separate each of the permanent magnets in the plurality of permanent magnets into first and second permanent magnet sections to form a respective pair of adjacent permanent magnets separated by an air gap in the third plurality of air gaps, wherein each of the air gaps in the third plurality of air gaps is aligned with a corresponding air gap in the first plurality of air gaps to segment the fault current limiter into segments.
