According to the data for the last five years, about 33.7% of the total fire causes were electricity, of which more than 81% was caused by arcs. Currently, in Korea, MCCB(Molded Case Circuit Breaker) and ELB(Earth Leakage Breaker) are legally required to be installed on distribution boards, but these do not have an arc detection function, so it is required an arc detection and blocking device, AFDD(Arc Fault Detection Device). Furthermore, in this study, data results were calculated through an arc wavelength analysis experiment of a smart AFDD(Arc Fault Detection Device) using IoT technology. If these results are continuously accumulated and data is constructed, it can be used not only as fire prevention but also as an accurate and objective point of the fire occurrence and as an identification criterion for the cause of the fire occurrence.
