摘要： The present invention describes systems and methods for determining current flow through a current-carrying utility asset. An exemplary embodiment can include measuring a first magnetic induction value at a first location near a targeted current-carrying utility asset and a second magnetic induction value at a second location near the targeted asset where the first location is a known distance from the second location; determining a correlation between a spatial angle and an electrical phase angle between the targeted asset and a second asset where the second asset contributes a first and second error component to the first and second magnetic induction values respectively; estimating error values for the first and second error components using the correlation between the spatial angle and the electrical phase angle; and estimating a current flowing through the targeted asset using the first and second magnetic induction values, the known distance, and the error values.

摘要： A system and method for determining non-linear load harmonics impact on the voltage distortion at the point of common coupling is disclosed. Briefly described, one embodiment is a method comprising metering voltage on an electric power system; metering current on the electric power system; determining a predicted voltage based upon the metered current; comparing the predicted voltage with the metered voltage; and determining a harmonic voltage component using a plurality of weights determined when the predicted voltage converges with the metered voltage.
