Abstract: In low voltage AC power supply and distribution lines,arc fault is the main cause of electrical fires,which brings serious safety hazards to the operation of power systems.In order to protect the electrical safety,the arc fault types are described,detection difficulties and current waveform characteristics of series arc fault in the residential power supply and distribution lines are analyzed.The advantages and disadvantages of detection methods based on arc mathematical model,arc physics feature and arc current voltage waveform are discussed.Several arc fault detection patents are exemplified and their shortcomings are analyzed.The future development direction of the series arc fault detection method is prospected.An high-precision identification algorithm based on multi-feature information fusion,deep learning and adaptive protection need to be further researched.

Key words: series arc fault, electrical fire, low voltage power distribution line, detection method
