摘要： A superconducting current limiter having at least one superconducting conductor (3) wound so as to form a coil (2) extending in a single plane and connecting a first electrical connection terminal to a second electrical connection terminal, an electrically insulating spacer (8) being arranged between two turns of the coil. The superconducting conductor (3) consists of at least two separate superconducting cables (5) wound in parallel and whose ends are electrically connected by the first electrical connection terminal and by the second electrical connection terminal, respectively. An electrically conductive spacer (12) is arranged between two of said separate superconducting cables (5), this electrically conductive spacer (12) being able to be traversed by a cooling fluid.

摘要： A superconducting current limiting dipole (L6), comprising a superconducting conductor (F6) wound so as to form a two-wire coil extending in a single plane, a layer of insulator (E1 to E11, H1) being arranged between two turns of said coil. The superconducting conductor (C1 to C6) consists of at least four separate superconducting cables (C1 to C6) wound in parallel and arranged in at least two pairs, each of the pairs being formed by two of said superconducting cables (C1 to C6) that are electrically connected to one another in a first connection area, and, in a second connection area, one of the superconducting cables of one pair is electrically connected to one of the superconducting cables of the other pair, the other superconducting cable of each pair being connected to an electrical connection terminal (T1, T2) or to an additional pair.

摘要： A method of protecting a high-voltage network comprising the steps for maintaining first controlled switches closed and second controlled switches open; measuring voltage and current on high-voltage interfaces; communicating the direction of the current to the other end of a high-voltage line; for each node: identifying a fault; verifying that the current is lower than the current interruption capability of the high-voltage interface switch and opening this switch.
