This article describes the calculation results of the effect of a fault current limiter (FCL) upon the interrupting condition imposed on a circuit breaker when a fault occurs at a distance of 1-8 km downstream from the load-side terminals of the FCL. For the purpose of comparison, we also look at the interrupting condition when the fault happens very close to the terminals of the FCL. The FCL in current-limiting operation was assumed to have a limiting element composed of either an inductance or a resistance. For all fault locations, the insertion of the resistive FCL proved to decrease not only the fault current, but also the rate of rise of the recovery voltage (rrrv). For the inductive FCL, the rrrv depends mainly upon the stray capacitance Cp of the limiting coil. Under short-line fault (SLF) condition, the introduction of the inductive FCL with Cp = 100 nF is shown to reduce the severity of the SLF transient by reducing the fault current and the rrrv. However, for all fault locations, the insertion of the inductive FCL with C p = 10 nF was found to decrease the fault current, while increasing the rrrv.
