PROBLEM TO BE SOLVED: To enable correction of minute current measured by a usual current sensor for an effect of electromagnetic induction by large current flowing through an adjacent current path.SOLUTION: A current measurement device is connected to current sensors for measuring current flowing through respective current paths, and includes correction means configured to correct a value of current for a first current path to zero when the value of current for the first current path is less than a first threshold value and a value of current for a second current path adjacent to the first current path is greater than a second threshold value that is greater than the first threshold value.SELECTED DRAWING: Figure 1 |
