Method and apparatus for electronic testing of electricity meters

METHODS AND APPLIANCES ARE PRESENTED TO ELECTRONICALLY VISUALIZE THE MEASURED ELECTRICAL ENERGY. A FIRST PROCESSOR (14) RECEIVES SIGNALS OF VOLTAGE AND CURRENT AND DETERMINES ELECTRICAL ENERGY. THE FIRST PROCESSOR (14) GENERATES A REPRESENTATIVE ENERGY SIGNAL OF THE DETERMINATION OF ELECTRICAL ENERGY. A SECOND PROCESSOR (16), CONNECTED TO THE FIRST PROCESSOR ABOVE, RECEIVES THE ENERGY SIGNAL AND GENERATES A REPRESENTATIVE VISUALIZATION SIGNAL OF THE ELECTRICAL ENERGY INFORMATION. A SCREEN IS CONNECTED (30) THAT RECEIVES THE DISPLAY SIGNAL AND SHOWS THE INFORMATION ON ELECTRICAL ENERGY. IN A FIRST ASPECT OF THE INVENTION, IT IS PREFERRED THAT THE FIRST PROCESSOR (14) DETERMINE ELECTRICAL POWER UNITS FROM THE VOLTAGE AND CURRENT SIGNALS AND GENERATE A REPRESENTATIVE ENERGY SIGNAL OF THE DETERMINATION OF SUCH UNITS AND SPEED TO WHICH THE UNITS ARE DETERMINED. IN ANOTHER APPEARANCE OF THE INVENTION, THE FIRST PROCESSOR DETERMINES AND SHOWS THE UNITS IN VATIOS, THE APPARENT REACTIVE ENERGY UNITS AND THE SPEED TO WHICH SUCH UNITS ARE DETERMINED. THE SCREEN (30) MAY PROVIDE INFORMATION ON THE DIRECTION OF ENERGY CIRCULATION.
