1. A method comprising:
receiving input data associated with a number of assets of an electric power delivery system;
identifying an event associated with a first asset of the number of assets based on a portion of the input data;
generating a number of delayed signals based on the input data;
generating a number of detection signals based on a difference between the delayed signals and the input data;
identifying a subset of the number of detection signals that satisfy a threshold;
sorting the subset of the number of detection signals based at least in part on when a frequency of the subset of the number of detection signals decreases, wherein each detection signal of the number of detection signals is associated with a respective timestamp;
determining that more than one of the detection signals are associated with a common timestamp;
sorting at least the more than one of the detection signals by value referenced to a system frequency of the electric power delivery system to determine a lowest value detection signal;
determining an onset of an event associated with the first asset based on the subset of the number of detection signals and the lowest value detection signal;
generating a display overlay for a portion of the input data associated with the event; and
transmitting the display overlay to a display for presentation via the display with the input data.
