Classification: CPC G | IPC G

Claim 15:
16. One or more non-transitory computer-readable media storing computer-executable instructions that, when executed by one or more processors, configure a computing device to perform acts comprising:
generating a time-series of voltage-changes for a meter;
assigning a time-series of voltage-changes to each transformer from among transformers less than a threshold distance from the meter, wherein the assignments are based at least in part on a statistical measure having a central tendency applied to time-series of voltage-changes of one or more meters indicated based on an existing record to be connected to the transformer;
determining a Pearson's Correlation Coefficient (PCC) value between the meter and each transformer within the threshold distance of the meter, using as input a time-series of voltage-changes of the meter and using the assigned time-series of voltage-changes of each transformer;
setting, for the meter, a reference PCC value to be an average of the largest and the second largest PCC value of the meter;
calculating voltage-correlation confidence rating (VCCR) values for the meter with each transformer that is less than the threshold distance from that meter, wherein the calculating is based at least in part on the determined PCC value and the reference PCC value; and
associating the meter to a transformer based at least in part on the VCCR value of the meter with each transformer that is less than the threshold distance from the meter,
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.
