Abstract: The invention relates to a device for identifying consumer devices in an electric network (1) with currents that can vary over time and said device has a measuring device (3) for measuring at least one current signal of the electric network on at least one measuring point, a storage medium (5) in which at least one consumer spectrum, determined in advance, is stored, a data analysis device (6) and an output device (7). In this case, the data analysis device (6) converts the measured current signals of the electric network (1) into a network signal, automatically generates a model in which the network signal can be linked with at least one consumer signal, stored in advance in the storage medium (5), of at least one consumer device (2a, 2b), and automatically analyzes the model for determining at least one consumer distribution in the electric network. The invention relates, moreover, to a process for operating the device.
