Patent ID: 7930118

Claim:
An electric energy monitor device for measuring the electrical energy usage of an electrical load powered by load conductors connected to a power source, the electrical load having a line cord comprising the load conductors, the line cord terminating in a plug having blades terminating the load conductors for connection to an electrical receptacle coupled to the power source, the device comprising: a body, the body being configured to allow at least one blade to pass through at least one opening in the body into the electrical receptacle, at least one current sensor for detecting a level of current, the current sensor being housed in the body and the current sensor comprising an inductor having at least one complete electrical turn in inductive communication with the load conductor when the blade extends through the opening in the body into the electrical receptacle such that an output voltage of the current sensor is a function of the level of current in the load conductor, a controller for receiving signals from the current sensor, and transmitting data either to a display for displaying data relating to electrical energy usage of the load, or to a remote data processing device for recording data relating to electrical energy usage of the load, or to both, the controller being housed in the body.
