Abstract
Provided is a collected current monitoring device. A transformer current acquisition unit acquires a current value Iof a current flowing through a part of a plurality of transformers. A total collected current calculation unit calculates a current value Iof a collected current supplied by a plurality of current collectors from the current value Iby using a following Equation (1): I=I×(M/M). A collected current acquisition unit acquires a current value Iof a collected current supplied by the current collector(s) other than one current collector. The collected current calculation unit calculates a current value Iof a collected current supplied by the one current collector by subtracting the current value Ifrom the current value I.
