Document Type and Number:
WIPO Patent Application WO/2022/044626
Kind Code:
A1
Abstract:
This arc detection device (1) comprises an acquisition unit (11) and a determination unit (12). The acquisition unit (11) acquires a measurement result for the voltage (V1) applied to one target power supply path (L0) from among a plurality of power supply paths (L1) through which power is supplied from a DC power supply (2). The determination unit (12) determines whether it is possible that an arc fault has occurred in the plurality of power supply paths (L1) on the basis of a specific frequency band component in the voltage (V1) measurement results acquired by the acquisition unit (11).
