Abstract
A method and apparatus is disclosed for determining the incident energy of a system. Specifically, there is provided a technique comprising measuring a voltage of an ac waveform, causing a resonant ring in the ac waveform, measuring a frequency of the resonant ring, computing a line impedance based upon the measured voltage and the frequency of the resonant ring, and computing a bolted fault current based on the line impedance and the measured voltage.
