Stéphan D. PICARD has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 12027843
    Abstract: Systems, methods, and computer-readable media are disclosed for high-speed falling conductor protection in electric distribution systems. An example method may include calculating, by a processor, at a first time, and for each phase, one or more first impedance values associated with one or more terminals of a transmission line. The example method may also include calculating, by the processor, at a second time, and for each phase, one or more second impedance values associated with the one or more terminals. The example method may also include determining, by the processor, that a rate of change of an impedance of the one or more terminals is greater than a threshold rate of change. The example method may also include determining, by the processor and based on the determination that the rate of change of the one or more terminals is greater than the threshold rate of change, that the transmission line has broken.
