| Abstract: | In this paper,the transient performance of a magnetic core fault current limiter(FCL) saturated by high temperature superconducting(HTS) DC bias winding is investigated by using both 3-dimensional(3D) field-circuit coupled simulation and magnetic circuit analysis.A high voltage is induced on the DC HTS winding during the fault current state.The induced voltage is computed and a short circuit coil for the reduction of induced voltage is studied.The numerical computations are verified by the experiment results on an FCL prototype. |
