Claim 0:
1. A method, comprising:
generating a meter time-series of voltage-changes of a meter;
assigning a transformer time-series of voltage-changes to each transformer, from among a plurality of transformers;
determining Pearson's Correlation Coefficient (PCC) values of the meter with respect to individual transformers of the plurality of transformers that are within a threshold distance of the meter, the PCC values being based at least in part on the meter time-series of voltage-changes of the meter and the transformer time-series of voltage-changes of each respective transformer;
setting a reference PCC value of the meter to be an average of the largest and the second largest PCC value from among the PCC values of the meter;
calculating voltage-correlation confidence rating (VCCR) values for the meter with respect to each transformer that is within the threshold distance from that meter, wherein the calculating is based at least in part on:
the reference PCC value for the meter; and
the determined PCC value for the meter with each respective transformer;

determining, based at least in part on the VCCR values for the meter with respect to each transformer that is within the threshold distance from that meter, a probability of the meter being connected to each transformer within the threshold distance of the meter; and
associating the meter to a transformer with which the meter has the highest probability of being connected,
wherein the associating forms at least part of an updated record, and
wherein the updated record is configured to indicate corrections of over-loaded transformers.
