Abstract
A method of electrical system fault detection and location determination includes measuring a baseline time domain reflectometry (TDR) waveform along a wire path of the electrical system and obtaining an operating TDR waveform along the wire path. The operating TDR waveform is compared to the baseline TDR waveform to derive a difference TDR waveform, and a difference energy is calculated utilizing the difference TDR waveform. The difference energy is monitored over time for peaks in the difference energy and potential electrical system faults are identified via the peaks in the difference energy.
