建立并测试了电感式超导故障限流器。它主要由铜线圈、超导管和铁芯同心排列组成。该装置本质上是一个变压器，二次绕组是管。该管直径为20厘米，高35厘米，由Bi2212陶瓷制成，采用部分熔融制造。该陶瓷具有V-I/sup /spl alpha//与/spl alpha//spl ap/5的电压电流特性。由1 /spl mu/V/em准则定义的临界电流密度约为1400 A/cm/sup / 2/。根据线圈匝数的不同，该装置的标称电流在130安至250安之间。在480 V电路的短路试验中，8 kA的预期故障电流被限制在标称电流的5倍左右。测试结果与正常工作（例如阻抗，交流损耗）和故障条件下的行为（即电流的演变）的详细模拟非常吻合
An inductive superconducting fault current limiter has been built and tested. It mainly consists of a copper coil, a superconducting tube, and an iron core which are concentrically arranged. The device is essentially a transformer with the secondary winding being the tube. The tube has diameter of 20 cm, a height of 35 cm, and is made of Bi2212 ceramic, fabricated by partial melting. The ceramic has the voltage current characteristic V-I/sup /spl alpha// with /spl alpha//spl ap/5. The critical current density defined by the 1 /spl mu/V/em criterion is about 1400 A/cm/sup 2/. Depending on the number of turns of the coil, the nominal current of the device was between 130 A and 250 A. In short circuit tests in a 480 V circuit, the prospective fault current of 8 kA was limited to about 5 times the nominal current. The test results are in good agreement with detailed simulations of both the normal operation (e.g. impedance, AC-losses) and the behaviour under fault conditions (i.e. evolution of the current).<<ETX>>
