Abrégé
(EN)
Methods and apparatus for electronically displaying metered electrical energy are disclosed. A first processor (14) receives voltage and current signals and determines electrical energy. The first processor (14) generates an energy signal representative of the electrical energy determination. A second processor (16); connected to said first processor; receives the energy signal and generates a display signal representative of electrical energy information. A display (30) is connected to receive the display signal and displays the electrical energy information. In a first embodiment it is preferred for the first processor (14) to determine units of electrical energy from the voltage and current signals and to generate an energy signal representative of the determination of such units and the rate at which the units are determined. In another embodiment the first processor determines and displays watt units, apparent reactive energy units and the rate at which such units are determined. The display (30) may provide energy flow direction information.
