Abstract: A method, apparatus, and computer-readable storage medium for detecting voltage anomaly in an electrical grid are provided. An electricity meter may collect voltage data by sampling a voltage waveform of the electrical grid at a preselected sampling rate; based on the voltage data, determine standard voltage waveform statistics of voltage of the electrical grid including statistical metrics; determine a range for the statistical metrics based on the standard voltage waveform statistics; at a preselected interval, calculate a statistical value of the statistical metrics of a present voltage waveform sampled at the preselected sampling rate for a preselected interval of the present voltage waveform; and in response to determining that the statistical value is outside of the range: capturing a predetermined number of cycles of voltage waveforms around the present voltage waveform, and sending an alarm to a remote computing device associated with the electrical grid.
