Abstract
A monitoring device which can monitor automatically and in real time the electric consumption in a house, in premises or any other building while controlling the total consumption of the complete electric installation in a predetermined area, the system including equipment for measuring (1) and indicating (5) the instantaneous consumption, and selection (4) and storage for various consumption levels. All of these operations are governed by control and processing equipment (3). There are also provided indicators for the consumed power (1) and equipment for entering (4) and displaying (5) data so that the user can control the accumulated consumption, set a limit value of the energy cost forecast and send a warning signal when such limit has been exceeded, and additionally prevent any devices from remaining connected when leaving the premises, this being extremely dangerous. The system takes measurements at different points in the installation and makes automatic connections/disconnections of certain loads in order to avoid overcurrents in the electrical network.
