Abstract :
A proper description of the nonlinear voltage-current relation of the superconductor is necessary for accurate analysis of the superconducting fault current limiters (SFCL). Discrepancies between the experimental results and the prediction of Bean´s critical state model were observed. Using a recently found unified nonlinear response function of type-II superconductors, the authors derive the current-voltage characteristic of metal-sheathed HTS conductor and compare it with experiments. Its relation to the operation of SFCL is also discussed
