Claim 7:
8. A system, comprising:
a memory device that stores connectivity information that associates meters and transformers and voltage data for a plurality of meters; and
a processing device that is configured to analyze the voltage data to maintain an association between at least one of the meters and a transformer by:
selecting a group of transformers that includes a selected transformer and a plurality of additional transformers, wherein the additional transformers are located within a predetermined geographic distance of the selected transformer;
selecting a set of meters using the connectivity information, wherein each meter is associated with one of the transformers in the group of transformers and the connectivity information associates a selected meter with the selected transformer;
determining a voltage profile for each meter in the set of meters using the stored voltage data that includes measured voltages for interval periods within a predetermined time range; and
for the selected meter:
comparing the voltage profile for the selected meter with voltage profiles for the remaining meters in the set of meters to generate a plurality of correlation coefficients;
identifying from the remaining meters a first meter that has a maximum correlation coefficient with respect to the selected meter;
identifying a first transformer associated with the first meter as a candidate transformer for the selected meter;
identifying a second set of meters from the set of meters that is associated with the candidate transformer based on the connectivity information;
comparing the voltage profile for the selected meter with voltage profiles for the second set of meters to generate a second plurality of correlation coefficients;
calculating a confidence factor for the selected meter and the candidate transformer by computing a weighted sum of (i) the maximum correlation coefficient associated with the first meter with respect to the selected meter and (ii) an average of the second plurality of correlation coefficients, wherein the confidence factor indicates a likelihood that the selected meter is connected to the candidate transformer via a resource distribution network;
calculating additional confidence factors for the selected meter and other candidate transformers selected from the group of transformers;
based on the confidence factor for the selected meter and the first transformer and the additional confidence factors for the selected meter and the other candidate transformers, selecting the first transformer; and
when the first transformer is the selected transformer confirming the connectivity information for the selected meter to associate the selected meter with the selected transformer.
