Serial-arc detection by use of Spectral Dispersion Index (SDI) analysis in a low-voltage network (270V HVDC)

•This series arc fault detection algorithm is performed by the current frequency analysis based on the calculation of the “Spectral Dispersion Index”.•The method is tested with resistive, inductive and switching appliances.•We propose a process of dynamic thresholding when calculating the spectrogra...
