Abstract
Disclosed implementations determine transient distortions, amplitude distortions, and/or periodic distortions present in a voltage signal measured from an electrical circuit at a location and use those distortions to determine a device type of a device operating on the electrical circuit at the location. In some examples, the voltage signal may be filtered into a plurality of sub-bands and one or more two-dimensional representations generated based on transient distortions, amplitude distortions, and/or periodic distortions determined in each sub-band. The one or more 2D representations may be provided to a deep neural network to determine a device type that generated the distortions on the electrical circuit.
