Abstract: Embodiments detect one or more events on an electrical grid. Embodiments use a sensor installed at an edge of the electrical grid to generate a sensor waveform at a first sampling rate corresponding to current and/or voltage signals. Embodiments transform the sensor waveform into multiple frequency bands and digitize the multiple frequency bands at a second sampling rate that is lower than the first sampling rate. Embodiments receive, by a pattern recognition machine learning algorithm at the edge, the digitized multiple frequency bands for events and predict, using the ML algorithm, an occurrence of the one or more events.
