Disclosed herein are systems for determining a broken conductor condition in a multiple-phase electric power delivery system. It has been observed that broken conductors pose a safety concern when occurring in the presence of people or vulnerable environmental conditions. Broken conductor conditions disclosed herein may be used to detect and trip the phase with the broken conductor, thus reducing or even eliminating the safety risk. Broken conductors may be determined using detected phase series arcing differences in one phase without commensurate differences in other phases. In various embodiments the phase series arcing attributes may be phase current monitored for decrement and/or phase resistance monitored for increase.
