APPARATUS AND METHOD FOR DETECTING THE ENERGY CONSUMPTION IN A LOCAL POWER SUPPLY SYSTEM

摘要

An apparatus for detecting energy consumption in a local power supply system having at least one central line and a plurality of sublines branching from the central line and connected to consumers includes at least one detection unit for centrally detecting the individual energy consumptions of the individual consumers, the detection unit having an analog-to-digital converter detecting electric voltage on the central line. An analog input of the analog-to-digital converter is connected to the central line. The detection unit has a plurality of input channels, each input channel being coupled to a measuring transformer integrated into one of the sublines for measuring the flow of current through said subline. The detection unit is configured to successively sample the input channels and determine individual energy consumptions in each subline based on measured current flow through sublines and detected voltage on the central line.
