US Patent Issued on June 3 for "Method and apparatus for detection of arbitrarily located single-phase open circuits by inverter-based resources" (New Mexico Inventor)

ALEXANDRIA, Va., June 4 -- United States Patent no. 12,322,974, issued on June 3.

"Method and apparatus for detection of arbitrarily located single-phase open circuits by inverter-based resources" was invented by Michael Ropp (Albuquerque, N.M.).

According to the abstract* released by the U.S. Patent & Trademark Office: "Methods, apparatuses, and systems for detecting arbitrarily located SPOs between a utility power source and a POI of an IBDER and mitigating the effects of such a SPO. Generally, a SPO will cause certain persistent, predictable variations and differences in voltages between phases. The standard deviations of the per-phase voltages can be calculated for each of a series of successive time intervals, and a difference value ...
