ELECTRIC ARC DETECTION DEVICE AND ELECTRIC ARC DETECTION METHOD |
摘要 |
The present invention easily detects an electric arc. An electric arc detection device (12) is provided with a current sensor (31), a power spectrum conversion unit (41) for converting the output of the current sensor (31) into a power spectrum, an interval value acquisition unit (42) for setting an interval value for a power spectrum measurement interval to an area value excluding a maximum area value when the measurement interval is divided into a plurality of areas, and an electric arc presence determination unit (43) for comparing the interval value with a threshold to determine the presence or absence of an electric arc. |
