Abstract
A Fault Current Limiter (FCL) comprising a magnetisable limb, an electrically conductive coil associated with the magnetisable limb and arranged to induce a field in the limb member and magnets spaced such that the coil is positioned intermediate the spaced magnets. Magnetisable shield elements are positioned at either end of the coil.
Claims18
A Fault Current Limiter (FCL) comprising:
- at least one magnetisable limb member;
- at least one electrically conductive coil associated with the magnetisable limb member and arranged to induce a field in the limb member;
- magnets spaced such that the electrically conductive coil is positioned intermediate the spaced magnets;
- and
- magnetisable shield elements disposed at opposed ends of the electrically conductive coil between the opposed ends of the coil and the magnets, wherein the magnetizable shield elements divert flux generated by the coil to a path away from adjacent closest surfaces of the magnets.
