Arc detection systems, arc detection methods, and computer-readable materials are not temporary.

Abstract

The invention relates to an arc detection system (100) comprising a first receiving unit (11), a second receiving unit (12), and a determining unit (13). The first receiving unit (11) receives the measurement of the current (l) flowing in the power line (ll) to which the current is supplied from the power supply (2) or the measurement of the voltage (lv) in the power line (ll). The second receiving unit (12) receives the operating information about the operation of the equipment (3) connected to the power line (ll). The determination unit (13) determines whether or not an optical coherence occurs in the power line (Ll) based on the results received by the first receiving unit (11) and the operational information received by the second receiving unit (12).
