Abstract
To protect a connected electrical load from anomalous electricity, an apparatus has a condition sensing unit configured to distinguish a power event type from among power event types from characteristics of an input electricity waveform accepted through an input port. The condition sensing unit indicates the power event type when a corresponding overvoltage criterion is met by characteristics of the input electricity waveform. A power control unit generates, responsive to a power event, a modulation signal that defines at least one amplitude notch in the input electricity waveform in accordance with the power event type. A switching mechanism electrically interposed between the input port and the output port transitions into conducting and non-conducting states in accordance with the modulation signal to superimpose the notch on the input electricity waveform.
