Claim:
1. A method, comprising: under control of one or more processors configured with executable instructions: calculating voltages at a secondary of each of a plurality of transformers; comparing the calculated voltages associated with each of the plurality of transformers to identify a transformer having calculated voltages that are lower than a first threshold, or having calculated voltages that have variance greater than a second threshold, based at least in part on calculated voltages of other transformers; determining that load changes measured by one or more meters associated with the identified transformer fail to justify the calculated voltages being less than the first threshold or having variance that is greater than the second threshold; and indicating a possibility of power diversion based at least in part on the failure of the load changes measured by the one or more meters associated with the identified transformer to justify the calculated voltages being lower than the first threshold or the calculated voltages having variance that is greater than the second threshold.
