Abstract
An electricity meter includes a power line interface circuit configured to generate measurements of parameters for at least two electricity transmission paths. The meter also includes a balance determination circuit configured to generate at least one balance metric that indicates a balance between the electricity transmission paths from the generated measurements. The meter further includes a communications circuit configured to transmit balance information to an external recipient responsive to the at least one balance metric.
Claims17
An electricity meter comprising:
- a power line interface circuit configured to generate measurements of parameters for at least two electricity transmission paths;
- a balance determination circuit configured to generate at least one balance metric that indicates a balance between the electricity transmission paths from the generated measurements, wherein the at least one balance metric is of the form:
- B=(Mn−Mm)/(|Mn|+|Mm|),
- wherein Mn comprises one of an energy (E), voltage (V), current (I), phase angle (θ), frequency (F), total harmonic distortion (THD), or total demand distortion (TDD) measured for an nth path and wherein Mm comprises a corresponding one of an E, V, I, θ, F, THD, or TDD measured for an mth path;
- and
- a communications circuit configured to transmit the at least one balance metric to an external recipient.

A system comprising:
- an electricity meter configured to generate measurements of parameters for at least two electricity transmission paths, to generate at least one balance metric that indicates a balance between the electricity transmission paths from the generated measurements, and to transmit the at least one balance metric over a communications medium, wherein the at least one balance metric is of the form:
- B=(Mn−Mm)/(|Mn|+|Mm|),
- wherein Mn comprises one of an energy (E), voltage (V), current (I), phase angle (θ), frequency (F), total harmonic distortion (THD), or total demand distortion (TDD) measured for an nth path and wherein Mm comprises a corresponding one of an E, V, I, θ, F, THD, or TDD measured for an mth path;
- and
- an application configured to receive the transmitted at least one balance metric from the communications medium.
