Abstract:
1. A method for determining a primary side voltage of a distribution transformer comprising: determining a first current flowing through a secondary winding of the distribution transformer at a plurality of time instants based on current meter data generated by a plurality of metered loads connected to a secondary side of the distribution transformer; determining a second current flowing through the secondary winding of the distribution transformer at the plurality of time instants based on the current meter data generated by the plurality of metered loads connected to the secondary side of the distribution transformer; determining a total current flowing to the plurality of metered loads for each of the plurality of time instants based on the first current at the plurality of time instants and the second current at the plurality of time instants; receiving a respective meter voltage from each of the plurality of metered loads at each of the plurality of time instants; determining a secondary side voltage of the distribution transformer at each of the plurality of time instants based on the first current, the second current, the total current, and the respective meter voltages at the plurality of time instants; and determining the primary side voltage based on the secondary side voltage determined at a corresponding one of the plurality of time instants.
