Abstract
An arc detection device includes an obtainer and a determiner. The obtainer obtains a measurement result for a voltage applied to one target power supply line among a plurality of power supply lines to which power is supplied from a DC power source. The determiner determines, based on a component of a specific frequency band in the measurement result for the voltage obtained by the obtainer, whether there is a possibility of an arc fault occurring in the plurality of power supply lines.
