COIL, COIL ASSEMBLY AND SUPERCONDUCTING FAULT CURRENT LIMITER

摘要

A coil (12, 112, 212) is described, the coil (12, 112, 212) comprising an electrically conducting element (18, 118, 218) defining a plurality of first turns (20, 120, 220) around a first axis (X1, X101, X201), wherein at least two first turns are adapted to carry a current in opposite senses around the first axis (X1, X101, X201); and a respective plurality of second turns (22, 122, 221, 222) around at least one second axis (X2, X102, X202, X203), wherein at least two second turns are adapted to carry a current in opposite senses around a respective second axis (X2, X102, X202, X203); wherein at least two first turns are connected in series via at least one second turn. A superconducting fault current limiter (400) is described, comprising a coil (12, 112, 212) as described above, the conducting element (18, 118, 218) of which comprises a superconducting material.
