以1MVA功率容量和短时间恢复为目标的中压级阻性超导限流器已被开发出来(<；2 S)。采用50m长的YBCO涂覆导线带，在1kV/1kA、动作时间为0.1kA的条件下，设计建造了一种超导模块化保护装置，为延长动作时间，将其与空芯电抗器并联，使故障极限时间提高到1 S。试验确定了该组合保护装置的电、热特性。该组合式故障限流器的极限电流达到583A，相当于1个S作用时间内的3.3倍限制倍数。
Resistive-type of superconducting fault current limiters (RSFCL) have been developed for medium voltage class aiming to operate at 1 MVA power capacity and short time recovery (< 2 s). A RSFCL in form of superconducting modular device was designed and constructed using 50 m-length of YBCO coated conductor tapes for operation under 1 kV / 1 kA and acting time of 0.1 s. In order to increase the acting time the RSFCL was combined with an air-core reactor in parallel to increase the fault limiting time up to 1 s. The tests determined the electrical and thermal characteristics of the combined resistive/inductive protection unit. The combined fault current limiter reached a limiting current of 583 A, corresponding to a limiting factor of 3.3 times within an acting time of up to 1 s.
