  • Patent number: 10382831
    Abstract: Various embodiments relate to disrupting signals (e.g., over Multimedia over Coax or from a service provider) to determine signal recovery. A first device may receive signals from a network. The first device may receive a first input to switch the received signals from a first communication path between the network and a second device, to a second communication path for a predetermined interval. The switching of communication paths may be done by a network disruption device. When the signals are switched to the second communication path, the signals may be blocked from being received at the second device. The network disruption device may then switch the signals from the first communication path to the second communication path to block the signals for the predetermined interval. The network disruption device may then switch the signals from the second communication path to the first communication path after the predetermined interval has expired.

  • Patent number: 10241142
    Abstract: Systems and methods presented herein are generally directed to the location and/or identification of a circuit within a circuital system. In one embodiment, a transmitter is configured for inducing signals upon a plurality of circuit lines (e.g., power lines, communication lines, lighting circuits, etc.) with each circuit line having a unique signal to identify it from other circuit lines. Each signal may be induced upon an individual circuit line by means of a inductive coupling clip coupled about the circuit line. The transmitter may be used at a distribution point of the circuit lines, such as circuit breaker box. A receiver can then receive a signal from a distal point on the circuit line to acquire the unique signal induced thereon and identify determine which inductive coupling clip is coupled thereto. For example, the signal may be decoded to display a number of the circuit line being tested.

  • Patent number: 9983242
    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.

  • Publication number: 20150091545
    Abstract: A method for assigning individual phase conductors at a first point to those at at least one further point in a polyphase energy distribution network, in particular in a three-phase network. In the case of mains operation, wherein a common reference time is determined for these points, and the time difference and/or phase difference of the phase voltage or the line-to-line voltage between the reference time of a zero crossing of the phase voltage are determined for these points. By a comparison of the time and/or phase differences at two different points the phase conductor of one point is assigned to a phase conductor of the further point which has the same to time and/or phase difference with respect to the common reference time. An additional loading of the energy supply network or an interruption of the mains operation is avoided by the method.

  • Patent number: 8972215
    Abstract: At least one parameter of a signal is determined, wherein the signal is a sinusoidal signal including noise, wherein the parameter includes at least one of a frequency of the signal, and an angle of a phase of the signal. The frequency of the signal is determined iteratively based on a linear relationship among the frequency of the signal, samples of the noise, and samples of the signal using a statistical correlation among the samples of the noise. During a current iteration the statistical correlation is updated based on the frequency of the signal determined during a previous iteration, and the samples of the signal are updated with values of the signal during a current period of time.

  • Patent number: 8970204
    Abstract: A wireless phasing voltmeter determines the phase difference between the voltage carried by a reference electrical conductor and a field conductor. The voltage signal from the reference conductor is detected by a first unit and compared to a precision 60 Hz wave form generated from a first 1 pps GPS signal. The phase difference between the wave form and the reference conductor, represented by nine data bits, is used to modulate a radio frequency carrier wave and transmitted via simplex transmission to a second unit near an electrical conductor in the field. The second unit receives the modulated carrier wave, decodes the phase angle difference and compares it to a second phase angle difference between the voltage on the field conductor and a second precision 60 Hz wave form generated from a second 1 pps GPS signal. The difference between the two phase differences determines the phase of the field conductor.

  • Publication number: 20150042307
    Abstract: The industry practice to detect and identify objects such as wires, cables, pipes and tuned coils is to inject a known tone from a tone generator into the object by conduction or induction, occasionally with tagging information. The invention is a tone detection apparatus, also known as the tone probe, to detect the presence of such injected tones that makes use of a microphone or audio electrical input of a mobile computer and software application running on the mobile computer such as a contemporary “smart-phone”. The use of a mobile computer reduces the cost of this tone probe and provides the ability to use mobile internet connection to communicate and store the tagging and location information about object under detection. The display of the mobile computer allows providing more information than a typical tone probe.

  • Publication number: 20150022180
    Abstract: A remote phase identification system identifies the unknown phase attribute of any energized conductor within a three-phase power distribution network. A base station at a reference location obtains a reference phase each GPS second and stores it on one or more servers. A field probe at a remote location obtains an instantaneous phase measurement at a GPS second and communicates this phase to a field client. The field client communicates with the server either by wireless Internet or satellite modem to compare its field location phase measurement with the reference location phase measurement taken at the same GPS second. Field client tagging reference phase configuration files are automatically created for any circuit. Configuration files can be named, saved, and loaded and are used by the field client to identify and display the unknown field location phase attribute. A field client can be any personal computer, smartphone, or personal digital assistant.

  • Publication number: 20140253091
    Abstract: A power measuring device stores in a set phase relation storage whether the load connected to a three-phase, four-wire power source is inductive, capacitive, or neither of them, in other words whether the phase currents are ahead, delayed, or matching phases with respect to the phase voltages, and determines whether the stored phase relation coincides with the determined phase relation. Then, the incorrect connection that cannot be verified in the prior art, more specifically the primary conductors of the current transformers of the current xfrms that are all arranged reversely while the voltage terminals are connected correctly, can be detected as an incorrect arrangement.

In the first connecting stage an electrical quantity between two of the first contact terminals is detectable. This electrical quantity is different from an electrical quantity in an uncoupled condition of the connectors. In the second connecting stage a further electrical quantity between at least two of the first contact terminals is detectable and different from the electrical quantity detected in the first connecting stage.
