We have defined this feature as the quench current-time characteristic, i.e. the Iq-τ characteristic of two kinds of SC cables, with and without a low resistive stabilizing matrix. The results proved that the different Iq-τcharacteristics were caused by the differnce of the current redistribution process where each SC strand quenches successively. Furthermore, it was pointed out by numerical simulation using an equivalent electrical circuit model that the difference in resisitivity of SC strand could be the reason for the various Iq-τ characteristics.}, pages = {191--194}, title = {Quench current level-time characteristics of AC insulated multi-strand superconducting cables}, volume = {7}, year = {1997} }
