Claim:
1. A method for determining a power consumption in an electrical installation including a plurality of electricity distribution branches, and an incoming main power line connecting the plurality of electricity distribution branches to an electrical power supply, the method comprising: measuring a first power on the incoming main power line to identify an overall power consumption by the plurality of electricity distribution branches and recording, as first measurement data, the first power measured on the incoming main power line; detecting a change in the power consumption in the electrical installation; measuring a second power on the incoming main power line to identify an overall power consumption by the plurality of electricity distribution branches after the change and recording, as second measurement data, the second power measured on the incoming main power line; collecting, by a transducer located in a specific branch of the plurality of electricity distribution branches, information relating to an electric current in the specific branch; determining, by circuitry based on the information collected by the transducer, whether the change occurred in the specific branch; determining, by the circuitry based on the first measurement data, the second measurement data and a result of the determining of whether the change occurred in the specific branch, an individual power consumption in the specific branch; and determining, by the circuitry when the specific branch does not include the transducer, the individual power consumption in the specific branch based on the first measurement data, the second measurement data and a plurality of information, wherein each of the plurality of information relates to a corresponding electric current in each of a rest of the plurality of electricity distribution branches, the rest excluding the specific branch, and the each of the plurality of information is collected by a corresponding transducer located in the each of the rest of the plurality of electricity distribution branches.
