Abstract

The installation of arc circuit breakers is being strengthened to prevent accidents such as electric shock and fire caused by Arc. Among arcs, serial arcs are difficult to detect with general arc detectors because there is not much change in load current when an arc occurs. Therefore, in this paper, unlike the existing Arc Fault Circuit Interrupters method, arc detection hardware is implemented using the FFT algorithm. FFT is suitable for serial arc identification because it can efficiently analyze high-frequency signals generated outside of normal AC signals. This study explains ARC detection circuits and the 2048-FFT based on radix-2 and radix-4, and presents hardware implementation results using FPGA. The implemented system detects the arc up to the frequency range of 122,880 Hz. Through simulation and FPGA board testing, it was confirmed that ARC was detected.
