WIPO Patent Application WO/2022/091715
Kind Code:
A1
Abstract:
This arc detection system (100) comprises a first acquisition unit (11), a second acquisition unit (12), and a determination unit (13). The first acquisition unit (11) acquires a measurement result of a current (I1) flowing through a feed line (L1) along which power is fed from a power supply (2) or a voltage (V1) in the feed line (L1). The second acquisition unit (12) acquires operation information about an operation of an apparatus (3) connected to the feed line (L1). The determination unit (13) determines whether an arc fault occurs in the feed line (L1) on the basis of the measurement result acquired in the first acquisition unit (11) and the operation information acquired in the second acquisition unit (12).
