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： Systems and methods for dynamic AC line voltage regulation are provided. A simple and cost-effective method for achieving AC line voltage regulation in AC systems including split-phase systems, of which the voltage for each voltage line may be regulated over a specified range, is provided. Buck and boost regulation is achieved for lowering or increasing the line voltage, respectively, with reference to the incoming grid voltage. Systems for dynamic AC line voltage regulation may comprise an AC/AC converter which uses fractionally rated switches and magnetics that handle only a fraction of the load current, resulting in lower costs. The use of an AC snubber further provides safe and robust switching of the main switching devices by eliminating failure prone switching sequences that are dependent on accurate assessment of voltage and/or current polarity for AC or bi-directional switches.
