Title:
ARC DETECTION DEVICE AND ARC DETECTION METHOD
Document Type and Number:
WIPO Patent Application WO/2016/143380
Kind Code:
A1
Abstract:
The present invention easily and accurately detects arc generation. The arc detection device (12) comprises a current sensor (31), a first filter (33), a second filter (34), a FFT processing unit (41) that generates high-frequency and low-frequency power spectrums, an arc detection unit (42) that detects an arc with the high-frequency power spectrum, a false arc mask unit (43) that determines a false arc with the low-frequency power spectrum, and an arc existence determination unit (44).
