摘要

分析了容性负载和感性负载对低压开关柜小电流电弧故障的影响。测量结果表明，特别是感应负载对电弧的频谱有一定的影响。可以对影响电弧电流的几个参数进行表征。可以看出，在具有几个不同连接负载的网格中检测电弧的机会取决于电弧的位置和所有负载对当前形状的影响。

Influence of Capacitive and Inductive Loads on the Detectability of Arc Faults

In this paper, the influences of capacitive and inductive loads on low current arc faults in low voltage switchgear are evaluated. Measurements show, that especially inductive loads have an influence on the frequency spectra of an arc. Several parameters of influence on the arc current could be characterized. It could be shown, that the chance to detect an arc in a grid with several different connected loads depends on the location of the arc and the influence of all loads on the current shape.
