D.C. railway power feeding system is protected from a short circuit fault by the D.C. high speed circuit-breaker and the fault current detection device called 50F. However, load currents increase in recent years, the setting of protection becomes difficult and the margin of the setting decreases. On the other hand, the fault current detection device of the old model might malfunction because load characteristics of recent inverter controlled electric vehicles are not considered. In this study, we clarify output characteristics of the fault current detection devices. In addition, we would like to report on notes in the setting of the fault current detection devices.
