A compensator for use in connection with the metering of electricity calculates multi-level losses due to loss devices such as transformers and transmission lines. The compensator calculates losses to delivered electricity due to the presence of such loss devices and can sum losses from multiple loss devices to determine the electricity being delivered at various points, or levels, in the transmission system.

Multi-level transformer and line loss compensator and method

A revenue accuracy meter and a method are provided for measuring the amount and quality of power received by a power customer across electrical power lines. The revenue accuracy meter preferably has a variation determiner for determining undesired variations in an electrical signal representative of power received by the power customer during a plurality of predetermined time periods. A power usage measurer is coupled in electrical communication with the variation determiner for measuring the power usage of a customer responsive to an electrical signal representative of a customer load. The meter further has a communications interface coupled in electrical communication with the variation determiner and the power usage measurer for communication signals representative of the power variations and the power usage. An energy management controller also preferably is connected to the communications interface for controlling power usage responsive to predetermined electrical command signals received from the power customer through the communications interface.
