ARC FAULT DETECTION USING CURRENT SIGNAL DEMODULATION, OUTLIER ELIMINATION, AND AUTOCORRELATION ENERGY THRESHOLDS
A series PV arc fault detection method and apparatus demodulates a current signal provided by a DC power source to an inverter to eliminate a DC component and periodic noise. Autocorrelation coefficients are generated from the demodulated current signal to monitor noise energy and variation and, based on the noise energy, a determination is made if an arc fault has occurred.

An arc suppressor fixable to a fusible element to suppress electrical arcs and prevent the spread of electric arc “burn-back.” The arc suppressor includes first and second inner members comprised of pre-cured silicone rubber, and first and second outer members comprised of an arc suppressing material (e.g., melamine). The inner and outer members form a sandwich around a portion of the fusible element, wherein the first inner member is located adjacent to a first surface of the fusible element and the second inner member is located adjacent to an opposing second surface of the fusible element. The first outer member is located adjacent to the first inner member and the second outer member is located adjacent to the second inner member. Mechanical fasteners tightly engage together the first and second inner members, the fusible element, and the first and second outer members.
