Electrical device for current conditioning comprising a primary spool (1), a secondary spool (2,3,4,6) which comprises a quenchable superconductor exhibiting a transition from a low resistive state to a high resistive state when a critical value of the electric current is exceeded, the secondary spool being coupled through a common part (8) of magnetic flux with the primary spool, the secondary spool further comprising a metallic member (6) which form a closed loop circuit, and a cryostat (5) providing a cooling of the secondary spool. The secondary spool (2,3) comprises at least one element (3) based on a substantial fraction of a non-quenchable conductor that exhibits a minor dependence of its resistance on current and magnetic field, and a fraction of the quenchable superconductor and at least one turn of the non-quenchable conductor (3) and the quenchable superconductor (2) is electrically jointed in series providing a closed loop circuit. |
