Systems and methods for intelligent event waveform analysis

A system for analyzing power events in an electrical/power system, the system comprising:

• memory;
• one or more sensors configured to sense at least one of a voltage and current signal in the electrical/power system;
• and
• one or more processors configured to:
• monitor at least one of a voltage and current signal using the one or more sensors;
• identify a power event in the electrical/power system from the monitored at least one of the voltage and current signal;
• in response to identifying the power event, capture waveforms of the monitored at least one of the voltage and current signal;
• determine energy-related information from pre-event measurements using the captured waveforms;
• determine energy-related information from post-event measurements using the captured waveforms;
• identify and/or derive and/or calculate additional information associated with the power event by comparing (a) determined energy-related information from pre-event measurements, with (b) the determined energy-related information from post-event measurements;
• and
• perform an action affecting at least one component in the electrical/power system, provide additional actionable information to event report(s), or provide extracted signal(s) to an automated event analysis system,
• wherein the energy-related information comprises energy-related signals, and the additional information includes identification of one or more duration variations in the energy-related signals by determining a duration of each half-cycle of a waveform from the captured waveforms.
