早在20多年前，美國電力研究院就開始研究和開發故障電流限製器。從研究情況來看
，這種設備可分為兩大類：第一類是 電dian力li線xian路lu上shang使shi用yong串chuan聯lian感gan應ying電dian抗kang，利li用yong感gan應ying電dian抗kang來lai限xian製zhi短duan路lu電dian流liu。其qi缺que點dian是shi設she備bei體ti積ji龐pang大da
，投tou資zi費fei用yong和he操cao作zuo費fei用yong高gao。第di二er是shi在zai電dian力li線xian路lu上shang串chuan聯lian常chang閉bi並bing聯lian旁pang路lu開kai關guan的de限xian流liu電dian阻zu

，故gu障zhang時shi打da開kai旁pang路lu開kai關guan，故gu障zhang電dian流liu即ji被bei 轉移到限流電阻上。這種方法包括：通過磁場 huoqitayoubingliandianzudegaoyaduanluqikongzhibuwendingzhenkongdianhu
，caiyongyoubingliandianzujirongduanyuanqiangzhandebingliankaiguanzhuangzhi，yijiqudongdaotijinruzhengchangzukangzhuangtai。youyuduijianceshijianheduanlushundongzuoshijianyouyaoqiu，suoyizhezhongfangfadexuduoquediandouyuduanluqidongzuokunnan，fanyingshijianchangyouguan。

　　故障電流限製順的新發展是使用高溫超導體。一種方案是：liyongchaodaopingbiceng，weiraopingbitiexin

，高(gao)溫(wen)超(chao)導(dao)體(ti)做(zuo)二(er)次(ci)線(xian)圈(quan)，使(shi)故(gu)障(zhang)電(dian)流(liu)僅(jin)僅(jin)通(tong)過(guo)普(pu)通(tong)線(xian)圈(quan)。當(dang)故(gu)障(zhang)電(dian)流(liu)發(fa)生(sheng)的(de)一(yi)瞬(shun)間(jian)

，而且也減速輕了斷路器的負擔。
