Abstract

In this paper, the arc fault test bench is built according to the UL1699 standard of the United States. The current waveforms of different modes of arc fault of linear load and the current waveforms of normal operation and series arc fault of common electrical equipment are collected. The phase space plane diagram of arc fault current and electrical equipment operation current is obtained by phase space reconstruction method. Based on fractal theory, the calculation method of information dimension suitable for analyzing the plane diagram is proposed, and the calculated information dimension is the first feature. The time domain characteristics of arc fault current waveform and electrical equipment current waveform are analyzed, and the zero-break time is calculated as the second characteristic. The algorithm is realized by Matlab software, and the extracted two characteristic quantities are used as double criteria to detect arc fault. The simulation results prove the feasibility and effectiveness of this method.
