Abstract
An apparatus for electronically communicating metered electrical power is disclosed. A first processor receives voltage and current signals and determines electrical power. The first processor generates an power signal representative of the electrical power determination. A second processor, connected to said first processor, receives the power signal and generates an output signal representative of electrical power information. A output device is connected to receive the output signal to output the electrical power information. The first processor determines units of electrical power from the voltage and current signals and to generates an power signal representative of the determination of such units and the rate at which the units are determined. The output devices may be one of a display, optical port and an option connector. When the output device is a display, the second processor may generate a disk signal representative of a rate of disk rotation in relation to the rate at which the units are determined, wherein the output signal to the display is representative of the units, the rate at which said units are determined, and the rate of disk rotation. The first processor, while concurrently determining units of electrical power, further may determine watt units, apparent reactive power units and the rate at which such units are determined, wherein the watt units, the apparent reactive power units and the rate at which such units are determined are displayed. The first processor may also meter multiple types of electrical power and generates power signals. The second processor, when connected to the optical port, generates an output signal in response to the power signals, wherein the generation of the output signal includes the multiplexing of the power signals into the output signal.
