Title: COLLECTED CURRENT MONITORING DEVICE
Abstract:
Provided is a collected current monitoring device. According to the present invention, a transformer current acquisition unit acquires a current value Ip for the current flowing in one portion of a plurality of transformers. A total collected current calculation unit uses formula (1) to calculate, from current value Ip, a current value Ia11 for the collected current supplied by a plurality of power collection devices. A collected current acquisition unit acquires a current value IX for the collected current supplied by the power collection devices other than one power collection device. A collected current calculation unit subtracts current value IX from current value Ia11 and thereby calculates a current value IY for the collected current supplied by the one power collection device. Formula (1): Ia11=Ip×(Ma11/Mp).
