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.
Claims3
A Fault Current Limiter (FCL) comprising:
- a structure having a plurality of repeating levels, rows, or ranks arranged one adjacent or above the other, each level, row, or rank including:
- a magnetisable limb member;
- an electrically conductive coil associated with the magnetisable limb member;
- and
- magnets spaced such that the magnetisable limb member and electrically conductive coil are positioned intermediate the spaced magnets,
- wherein an outer portion of the structure comprises an outer magnetisable limb member extending between spaced magnets which outer magnetisable limb member is free from an associated electrically conductive coil.
