摘要

电弧波形特征可以用各种方法来评估，以识别危险电弧故障条件的存在。讨论涵盖了电弧现象及其如何在低压配电电路中产生，以及危险条件与可能错误地模拟电弧故障存在的条件的隔离。许多波形特征和条件支持危险电弧故障的检测，并促进更强大的设计，能够承受不必要的跳闸条件。

Arc Fault Detection and Discrimination Methods

Arc waveform characteristics can be evaluated with various methods to recognize the presence of hazardous arc fault conditions. Discussion covers the arc phenomena and how it is generated in a low voltage electrical distribution circuit, as well as the isolation of the presence of hazardous conditions versus conditions that could falsely mimic the presence of an arc fault. Many waveform characteristics and conditions support the detection of hazardous arc faults and foster a more robust design, capable of withstanding unwanted tripping conditions.
