US Patent Issued to L3Harris Technologies on Dec. 2 for "Multi-phase AC voltage fault detection based on virtual voltage" (California Inventor)

ALEXANDRIA, Va., Dec. 2 -- United States Patent no. 12,489,288, issued on Dec. 2, was assigned to L3Harris Technologies Inc. (Melbourne, Fla.).

"Multi-phase AC voltage fault detection based on virtual voltage" was invented by Lixin Tang (Irvine, Calif.).

According to the abstract* released by the U.S. Patent & Trademark Office: "In an embodiment, voltage fault detection is performed for alternating current (AC) multi-phase power systems based on a reconstructed or virtual voltage signal derived from voltage samples captured in a shortened sample window to reduce fault detection time. The embodiment of the present disclosure constructs the virtual voltage signal (emulating the root mean square (RMS) voltage of any of the phases) from the v...
