An arc detector including a sensor detecting a radio frequency signal is provided to remove an arcing event quickly and effectively. An arc detector comprises the followings: an arcing radio frequency property indicating an arcing event generated in a power distribution unit(28); a memory(16) storing a noise radio frequency property indicating a back ground electric noise; a sensor detecting radio frequency signal(26) wirelessly propagated from the power distribution unit; a processor(14) including a comparator which compares a frequency property in order to discriminate a generation of the arcing event; and a arc alarm generator(19) producing an arc fault signal(18).
