✦ Synopsis
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 wires that have different critical currents were bifilar wound. Two type of connections have been tested. In the first, the pair of trigger and limiter solenoids were connected antiparallel, whereas in the second, they were connected antiseries. On each connection, the fault current limiting test was performed by short-circuiting a resistive load suddenly. After opening the load circuit a few seconds, the reclosing of the circuit was performed successfully. Then recovery time was investigated. The series type NRSFCL is selected for next research and development.
