Patent number: 8142881Abstract: A superconductor for mitigating the effects of local current disruptions in a superconducting filament. The superconductor comprises superconducting filaments covered by a medium in electrical communication with the filaments. The covering medium has anisotropic conductivity, the conductivity in a direction substantially aligned with the filaments being selected to stabilize the superconductor near the critical temperature, and the conductivity of the covering in a direction substantially perpendicular to the filaments being selected to permit controlled current sharing between the filaments, especially when a filament is compromised, while simultaneously limiting alternating current (ac) losses. In various embodiments, the covering comprises a wire mesh having longitudinal wires made of a first material having a first conductivity, and transverse wires made of a second material having a second conductivity, different from the first conductivity.Type: GrantFiled: July 27, 2010Date of Patent: March 27, 2012Assignee: American Superconductor CorporationInventor: Cornelis Leo Hans Thieme
