Based on the resistance response of high temperature superconducting (HTS) YBCO tape under overcurrent, a physical model of compact three-phase concentric HTS cable under fault current was established using adiabatic approximation. We consider the endurance criteria of no irreversible damage to the superconducting tapes and no significant vaporization of LN2. The fault current endurance capability of concentric HTS cable was obtained at different fault currents. The safety of the superconducting cable can be ensured by adding current limiting device to reduce the fault current magnitude or by improving the relay system to reduce the protection action time.
