Abstract
An electric power metering device which includes a current sensor, an electronic measurement and rectifier circuit, a processing circuit and a transmitter connected to the processing circuit to transmit power messages to an electric power measurement receiver. An electric current integration capacitor is connected to the current sensor via a rectifier circuit. A switch is commanded by a threshold detector to supply to the processing circuit and the transmitter power accumulated in the capacitor when its electric voltage has exceeded a predefined voltage threshold. A power message representative of a quantity of electric power is then transmitted. A power metering method includes transmission of a power message when a capacitor voltage has reached a voltage threshold.
