Abstract

See full text

An arc detection system includes an obtainer and a determiner. The obtainer obtains a measurement result for current flowing in a power supply line 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 current obtained by the obtainer, whether an arc fault has occurred. The determiner determines that the arc fault has occurred when a specific time for which the component of the specific frequency band is at least a threshold is longer than an occurrence time in which an arc can occur when a device is attached to or detached from the power supply line.
