This paper is studying the low voltage arc fault circuit interrupters (AFCI) based on FPGA Signal detection. The arc fault generator is designed to generate artificial low voltage series arc faults. The AFCI signal detection circuits are tested by using the measured voltage and current waveforms from the testing circuits. It is expect to develop high performance signal detection circuits and the key component using in AFCI. Finally, the experimental data with serial arc faults are used to test the detecting methods and compare with the commercial devices. The purposed detecting methods can effectively detect the occurring of series arc faults, and the probability of malfunction is low.
