- Abstract
Since direct fault arc current is lower than the normal current value, it cannot be discovered by over-current protection; On the other hand, the arc is so dangerous. Therefore, it's imperative to research on direct current (DC) arc. In this paper, with a large number of current data through experiments of DC arc, we analyze the data with Haar wavelet transform and FIR (finite impulse response) respectively, and then compare the filtered high frequency signal, proving that Haar wavelet transform can help analyze the frequency spectrum of the arc and recognize the characteristics of DC arc.
