Fault current limiter (FCL) is expected as an apparatus not only suppressing an overcurrent caused by short-circuit fault but also improving an instantaneous voltage drop. In this paper, the improvement effect of fault current limiter on the instantaneous bus voltage drop was investigated based on circuit theory. We assumed that an FCL was installed at a bus exit and a three-phase short-circuit fault occurred. Two types of FCL were considered, i.e., an inductive FCL and resistive one. In case that the relatively large limiting impedance is used, the bus voltage can be kept higher level by the resistive FCL than the inductive FCL which has the same magnitude of limiting impedance as the resistive one. The limiting impedance required to keep the bus voltage a specified level by the resistive FCL is smaller than that by the inductive one. From the results obtained in this paper, it is found that the resistive FCL is more desirable for the improvement in the bus voltage drop.
