Abstract

An arc fault detector, an electrical device having the arc fault detector, and a method of controlling the electrical device. The arc fault detector includes a current detector to detect current flowing through a plurality of loads in an electrical device, a filter unit to pass current having a frequency equal to or higher than a predetermined cut-off frequency from the frequency of the detected current, a comparison unit to compare a voltage of the passed current with a predetermined threshold voltage and output a comparison signal based on a comparison result, and a controller to determine whether an arc fault has been generated by comparing the comparison signal with a predetermined reference arc fault signal, determine a load having the arc fault from among the plurality of loads, and control cut-off of power to the determined load.
