Title: Innovations by David Francis Klein

Introduction

David Francis Klein is a notable inventor based in Glenview, IL (US). He has made significant contributions to the field of electrical engineering, particularly in the area of power distribution networks. With a total of four patents to his name, Klein's work focuses on enhancing the reliability and efficiency of electrical systems.

Latest Patents

Klein's latest patents include an "Earth fault sectionalizer for electric power distribution network." This innovative system and method identify earth faults in resonant grounded medium voltage networks that utilize a REFCL compensation system. The method derives a zero-sequence real power from phase voltage to ground on each phase and aligns it with the magnitude of a zero-sequence voltage provided by the REFCL compensation system. It determines fault occurrences based on the alignment of zero-sequence real power and voltage exceeding predetermined thresholds.

Another significant patent is the "Normally open tie pulse testing." This control system and method are designed for tie point fault interrupter and sectionalizing recloser devices in electrical grid feeders. The technique enables automated sectionalizing reclosers to isolate faults and restore load based on pulse count, rather than requiring source re-energization. The system initiates a pulse-testing sequence upon detecting loss of voltage, distinguishing transient faults from persistent ones.
