Arc Fault Detection Device and its Development Trend

Article Preview

Abstract:

Arc-fault is an important cause for fire.In order to ensure safety utilization of electric power, more attention should be paid to designing and using arc-fault detecting instruments. The article is an analysis of arc fault and its causes. By analyzing the current signal, discover its characteristics. Through analysis the characteristic, it was found that wavelet transformation is good for analyzing the current signals. An arc fault detection was designed based on wavelet transformation. At last, analysis of the arc fault detection development in China.
