Abstract :
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.
