利用高温超导体，构建并测试了超导故障限流器模型。超导体和作为换向开关的真空断流器用旁路线圈并联连接。当故障电流流过本设备时，由于超导体中的电压降，超导体被淬灭，电流传递到并联线圈。并联线圈中的大电流驱动真空灭弧器的磁斥力机构。由于真空灭流器的打开，超导体中的电流被断开。通过使用该装置，可以很容易地减少电流在超导体中的流动时间。另一方面，并联线圈的大电抗也容易限制故障电流
Using a high-temperature superconductor, we constructed and tested a model superconducting fault current limiter (SFCL). The superconductor and the vacuum interrupter as the commutation switch were connected in parallel using a bypass coil. When the fault current flows in this equipment, the superconductor is quenched and the current is transferred to the parallel coil because of the voltage drop in the superconductor. This large current in the parallel coil actuates the magnetic repulsion mechanism of the vacuum interrupter. Due to the opening of the vacuum interrupter, the current in the superconductor is broken. By using this equipment, the current flow time in the superconductor can be easily minimized. On the other hand, the fault current is also easily limited by large reactance of the parallel coil
