In this paper, we investigate the recovery process of resistive superconducting fault current limiters (R-SCFCLs) after fault clearance. The R-SCFCL module consists of an MCP-BSCCO-2212 bulk coil. A short-circuit test showed that an assembly containing 12 R-SCFCL modules is able to limit a prospective fault current of about 99 to just 11 kA peak within the first half-cycle of current (under Vo = 1 kV rms ). The current limiting behavior and the recovery process were analyzed by mean of simulations considering the E-J curve and the heat exchanges with the liquid nitrogen bath and between the components of each R-SCFCL module. Simulations of recovery under load and without load were done.
