Abstract
The present invention relates to a current sensor which measures alternating electromagnetic wave and a current breaker using the same, and the current sensor for alternating current is characterized in that it includes a sensor part arranged at a separation distance from the power wire through which alternating current is flowing; and a means of detecting alternating current by measuring the electromagnetic wave generated across the above sensor part by the electromotive force induced by the alternating current flowing through the above power wire, and in that the above means of detecting alternating current includes an amplifier.
