Claim 10:
11. A system, comprising:
a plurality of meters;
a plurality of transformers;
a computing device, configured to determine connectivity between meters and transformers, by performing a method comprising:
generating a time-series of voltage-changes for each of the plurality of meters;
assigning a time-series of voltage-changes to each transformer, wherein the assignments are based at least in part on a statistical measure having central tendency applied to the generated time-series of voltage-changes of one or more meters indicated to be connected to the transformer based on an existing record;
determining a Pearson's Correlation Coefficient (PCC) value between a meter and each transformer within a threshold distance of the meter, based at least in part on the time-series of voltage-changes generated for each meter and based at least in part on the assigned time-series of voltage-changes of each transformer;
setting, for each meter of the plurality of meters, a reference PCC value to be an average of the largest and the second largest PCC value of that meter;
calculating voltage-correlation confidence rating (VCCR) values for each 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 each of the plurality of meters to a transformer based at least in part on the VCCR value of each meter with each transformer that is less than the threshold distance from that 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.
