US Patent Issued to MERSEN USA EP on March 17 for "Arc fault detection using current signal demodulation, outlier elimination, and autocorrelation energy thresholds" (Massachusetts, Florida Inventors)

ALEXANDRIA, Va., March 17 -- United States Patent no. 12,578,375, issued on March 17, was assigned to MERSEN USA EP CORP. (Boonton, N.J.).

"Arc fault detection using current signal demodulation, outlier elimination, and autocorrelation energy thresholds" was invented by Roy A. Ball (Coral Springs, Fla.), Jonathan C. Kim (Brighton, Mass.) and Bradley M. Lehman (Belmont, Mass.).

According to the abstract* released by the U.S. Patent & Trademark Office: "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 ...
