Abstract
A system for identifying an arc fault in a wire, the system comprising a controller operably connected to a first load via first wire; the controller configured to supply a current to the first load, wherein the controller is operable to measure and filter the first voltage on the first wire with a bandpass filter having a selected pass band to select and retain spectral content, amplify the retained spectral content, and identify an envelope of the amplified retained spectral content. The controller also operable to measure a first current in the first wire and correlate changes in the first current with a characteristic of the amplified retained spectral content to identify an arc fault, wherein the characteristic includes a buffered envelope as a signal indicative of the amount of energy in the selected passband frequency range.
