摘要：
An arc is detected easily. An arc detector (12) includes a current sensor (31), a power spectrum conversion unit (41) that converts an output from the current sensor (31) to a power spectrum, a section value obtaining unit (42) that divides an arc measurement section for the power spectrum into a plurality of regions, and obtains, from region values for the plurality of regions excluding a maximum one of the region values, a region value to be a section value of the arc measurement section, and an arc determination unit (43) that determines a presence of an arc by comparing the section value with a threshold.
