Patent number: 11722168Abstract: A method includes computing electrical phase of electrical metering devices including obtaining data indicating zero-crossing times at first and second metering devices. A time difference between the zero-crossing times may be determined. In a first example, the time difference may be based at least in part on calculations involving a first value of a first free-run timer on a first metering device, a second value of a second free-run timer on a second metering device, the time of reception of a packet, and a latency defined by a time taken for the packet to propagate through at least one layer of at least one of the first metering device and the second metering device. A phase difference between the first zero-crossing and the second zero-crossing may be determined, based at least in part on the determined time difference.Type: GrantFiled: August 3, 2022Date of Patent: August 8, 2023Assignee: Itron, Inc.Inventors: Philippe Chiummiento, Matthieu Pichot, Guillaume Descamps, Fabrice Monier

Patent number: 11411598Abstract: Techniques for computing electrical phase of electrical metering devices are described. In an example, data indicating zero-crossing times at first and second metering devices is obtained. A time-difference between the zero-crossing times may be determined. In a first example, the time-difference may be based at least in part on calculations involving a first value of a first free-run timer on a first metering device, a second value of a second free-run timer on a second metering device, and a time of a transmission between the metering devices. In a second example, the time-difference may be based at least in part on calculations involving a start or end time of a time-slot of a spread spectrum radio frequency transmission scheme. A phase difference between the first zero-crossing and the second zero-crossing may be determined, based at least in part on the determined time-difference.Type: GrantFiled: May 29, 2019Date of Patent: August 9, 2022Assignee: Itron Global SARLInventors: Philippe Chiummiento, Matthieu Pichot, Guillaume Descamps, Fabrice Monier
