Detecting Arc Faults in AC Circuits

Bradley Lehman

ECE Professor Bradley Lehman awarded patent for creating a “Method for AC arc fault detection using multidimensional energy points”.

Abstract Source: USPTO

A method for detecting an arc fault in AC circuits. The method includes monitoring disturbances in an AC voltage signal by analyzing multi-dimensional energy points. A voltage signal is captured and the zero-crossing, minimum peak, and maximum peak are identified. Arcing signatures between the maximum and minimum peaks of the captured AC voltage signal are analyzed to detect an arc fault.
