Superconductor fault current limiters (FCL) have proven to be the enabling technology to provide a solution to the blackouts of the power grid. The proposal will focus on the design, building, and testing of a low AC loss MgB2 coil for a FCL which will improve the power grid's reliability and availability. The design aspects will include thermodynamic and electromagnetic modelling to optimize the superconducting coil and a cryogenic system in order to cool the coil to 20-25 K. The expected outcomes are a demonstration of the first prototype MgB2 FCL for industrial application, an understanding of the AC loss mechanisms, electromagnetic and thermodynamic modelling to ensure FCT reliable operation under steady state and transient conditions.
