A superconducting fault current limiting device for electric power systems has been investigated to find out its feasibility. Non-inductive reactor type fault current limiter has been constructed using metal superconductor. Two bifilar wound solenoids were connected in antiparallel or antiseries. On each connection, the fault current limiting test was performed by short-circuiting a resistive load suddenly. The recovery (normal-to-superconductive state transition) time after the current limiting mode has been studied using small scale model of fault current limiter for the low voltage distribution line. The results reveal that the current limiter could be operated under repetitive fault current accident which was removed within a few cycle of the limiting mode. The recovery time is a function of the dissipated energy under current limiting mode. Test results are presented.
