故障电流限制器有望成为高温超导体在电力工程中的首批应用。当超过临界电流时，利用超导体的固有特性从零（或在AC电流的情况下接近零）电阻状态转变为高电阻状态是快速作用故障电流限制器的基础。在本文中，作者报告了测试结果（43 kVA标称功率：450 V RMS和95 A RMS），并与理论模拟进行了比较。电路分析用于研究设计问题并提取短路应用期间超导材料（BSCCO 2212）的特性。EMTP仿真是用来预测故障电流限制器的行为，在公用事业网络，以协调与其他设备。
Fault current limiters are expected to be amongst the first applications of high-temperature superconductors in power engineering. The use of the intrinsic property of a superconductor to transit from a zero (or near zero in the case of AC currents) resistance state to a highly resistive state when the critical current is exceeded is the basis for a fast acting fault current limiter. In this article, the authors report test results (43 kVA nominal power: 450 V RMS and 95 A RMS) and comparisons to theoretical simulations. Circuit analysis is used to study design issues and to extract the superconducting material's (BSCCO 2212) properties during the application of the short-circuit. EMTP simulation is employed to predict fault current limiter behaviour in the utility network in order to coordinate with other equipment.
