Title:
ARC DETECTION SYSTEM, ARC DETECTION METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2022/091716
Kind Code:
A1
Abstract:
This arc detection system (100) comprises a first acquisition unit (11), a second acquisition unit (12), and a determination unit (14). The first acquisition unit (11) acquires a measurement result for current (I1) flowing through a feeding path (L1) to which power is supplied from a power supply (2), or for voltage (V1) in the feeding path (L1). The second acquisition unit (12) acquires fluctuation information regarding a fluctuation in a load (31) of a device (3) connected to the feeding path (L1). The determination unit (14) determines, on the basis of a specific frequency band component of the measurement result acquired by the first acquisition unit (11) and the fluctuation information acquired by the second acquisition unit (12), whether an arc fault has occurred in the feeding path (L1).
