A short sequence of individual phase measurements are displayed as dots inside a static phase attribute display circle. The 3 primary, 12 secondary, and 6 three-phase attributes are displayed around the outside of the phase circle. When using a touch screen Smartphone or Tablet display device, the user simply touches inside the phase circle to rotate the dots around the center of the phase circle, so they line up with the known conductor phase attribute.

    Abstract: A wireless mesh network is configured to manage a power grid. Each node within the wireless mesh network is configured to detect and classify voltage fluctuations in power supplied by an upstream transformer coupled to the power grid. When a given node detects a particular type of fluctuation (i.e., an “event”), the node generates a timestamped event classification that reflects the type of event and a time when the event occurred. A server configured to manage the wireless mesh network receives timestamped event classifications from each node within the wireless mesh network and then performs a time correlation with the received timestamped event classifications to determine which nodes detected similar events. When two or more nodes detected the same event at similar times, the server determines that those nodes are coupled to the same transformer.

  • Patent number: 9871701
    Abstract: A method in a communication system (20) including endpoints (24) that connect to one another using cable channels, includes injecting one or more test signals to a cable channel, which has first and second ends and is potentially connected to a first endpoint at the first end and to a second endpoint at the second end. One or more serial measurements are performed on the cable channel so as to sense the test signals. Based on the serial measurements, a decision is made as to which of the first and second endpoints are indeed connected to the cable channel.

  • Patent number: 9664712
    Abstract: A MOCT metering system includes a cutoff module that ensures zero output when values from an optical module fall below a threshold value. The cutoff module includes an RMS to DC converter that drives a comparator. The comparator drives a switch that causes the cutoff module to pass through the measured signal unmodified if above a threshold value and to output a zero voltage signal if below a threshold value.

  • Patent number: 9562934
    Abstract: A technique for determining performance characteristics of electronic devices and systems is disclosed. In one embodiment, the technique is realized by measuring a first response on a first transmission line from a single pulse transmitted on the first transmission line, and then measuring a second response on the first transmission line from a single pulse transmitted on at least one second transmission line, wherein the at least one second transmission line is substantially adjacent to the first transmission line. The worst case bit sequences for transmission on the first transmission line and the at least one second transmission line are then determined based upon the first response and the second response for determining performance characteristics associated with the first transmission line.
