Abstract
A superconducting fault current limiter () is shown. It comprises a cryostatic cooling system () for containing a cooling medium (), a superconducting wire () immersed in the cooling medium () and configured to carry a current, the superconducting wire () becoming non-superconducting above a critical current density, and a plurality of heat dissipation elements spaced along and projecting from the superconducting wire (), wherein the heat dissipation elements have an electrically insulating coating, and whereby the heat dissipation elements transfer heat from the superconducting wire () into the cooling medium ().
