Abstract: Systems, methods, and devices are provided for determining a maintenance mode of one or more merging units of an electric power delivery system using an intelligent electronic device that may rely on communication from wired (or wireless) electrical measurement devices. The intelligent electronic device may be a line relay. The merging units may provide data to the line relay including at least one bit indicating a maintenance mode of each merging unit. If a maintenance mode bit from a particular merging unit indicates that the merging unit is in the maintenance mode, logic of the line relay may determine if a maintenance mode override is received. If so, the line relay may disregard the maintenance mode bit and process the data from the merging unit. If the logic determines that the merging unit is in the maintenance mode, the line relay may force data from the merging unit to zero.
