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.
