Beschreibung
Zusammenfassung:	Provided is a collected current monitoring device. A transformer current acquisition unit acquires a current value Ip of a current flowing through a part of a plurality of transformers. A total collected current calculation unit calculates a current value Iall of a collected current supplied by a plurality of current collectors from the current value Ip by using a following Equation (1): Iall=Ip×(Mall/Mp). A collected current acquisition unit acquires a current value IX of a collected current supplied by the current collector(s) other than one current collector. The collected current calculation unit calculates a current value IY of a collected current supplied by the one current collector by subtracting the current value IX from the current value Iall.
