Abstract
The present disclosure relates to a current measuring device comprising: a plurality of unit modules which are provided with mutually different grounds and are connected in series; a power unit which supplies high-voltage DC or AC power to the plurality of unit modules via a line; and a current sensor which measures a current flowing through the line.
Claims4
A current measuring device, comprising:
- a plurality of unit modules which are provided with mutually different grounds and are connected in series;
- a power unit which supplies high-voltage DC or AC power to the plurality of unit modules via a line;
- and
- a current sensor which measures a current flowing through the line,
- wherein the current sensor is provided with a ground from an adjacent unit module that is closest to the current sensor among the plurality of unit modules such that a voltage difference between a measurement point and a ground terminal of the current sensor is equivalent to a voltage drop across the adjacent unit module.
