ABSTRACT:
Methods and apparatus for electronically displaying metered electrical energy are disclosed. A first processor receives voltage and current signals, determines electrical energy and generates an energy signal representative of the electrical energy determination. A second processor receives the energy signal and generates a display signal representative of electrical energy information. A display receives the display signal and displays the electrical energy information. In a first embodiment, it is preferred for the first processor to determine units of electrical energy and the rate at which the units are determined. The second processor generates a display signal representative of the units and the rate. The second processor may also generate a disk signal representative of an equivalent rate of disk rotation in relation to the rate at which the units are determined and energy flow direction information for display. A converter may also be provided for converting an electrical output signal to light. The second processor, connected to the converter, generates the electrical output signal in response to the energy signals, wherein the output signal includes a multiplexed arrangement of the energy signals.
