Abstract
The present invention provides an improved method of identifying which electrical conductor is supplying a signaling-point that is located on that conductor, in the electrical grid. The present invention makes the identification by measuring currents flowing into and out of a common connection-point, such as a power bus, and analyzing concurrent portions of these currents to determine whether they are ingress-current or egress-current over the analysis-intervals, and by a subsequent intra-bus and inter-bus analysis of the ingress/egress patterns. This is in contrast to prior art systems that rely on the measurement of signal strength, an approach that does not take best advantage of information in the signal because it fails to consider polarity of instantaneous voltages, reflective of the direction of current flow, or the intra-bus and inter-bus ingress/egress current-relationships.
