  • Patent number: 8791688
    Abstract: The technology relates to detecting the wiring phase of an unknown phase voltage relative to a reference phase voltage in an electric power distribution system having a polyphase power line. In order to reliably detect the wiring phase at the remote location relative to a reference wiring phase even if the remote location is at a larger distance from the reference location, at least one relay location is arranged between the reference location and the remote location and connected to the wiring phase of the polyphase power line. A first phase relation is detected between the reference wiring phase voltage at the reference location and the wiring phase voltage at the relay location. A second phase relation is detected between the wiring phase voltage at the relay location and the wiring phase voltage at the remote location. The wiring phase of the remote location relative to the wiring phase at the reference location is detected based on the first phase relation and the second phase relation.

For example, the signal may be decoded to display a number of the circuit line being tested.

    Abstract: Several systems and methods for monitoring the proximity of a device to a power line are disclosed. Electric field monitoring systems are mounted to the device and include a plurality of electric field sensors and a monitoring system base unit. Each electric field monitoring sensor senses the strength of a magnetic field in which the sensor is positioned and transmits a corresponding magnitude output signal to the base unit when polled by the base unit. If a sensor reports a magnetic field exceeding a threshold, the frequency of polling for that sensor may be increased. If a sensor reports a magnetic field exceeding another (possibly identical) threshold, an alarm may be activated, movement of the device may be limited or stopped or another action or a combination of actions may be taken.

  • Patent number: 8314603
    Abstract: A network cable includes a data cable with cable connectors at opposing ends. A tracer optical waveguide is connected to the data cable, e.g., within the same jacket or by connectors such as heat shrink tubing. The ends of the tracer optical waveguide are physically separate from corresponding ends of the optical waveguide, e.g., the ends of the tracer optical waveguide furcate from the data cable. In use, a light signal is introduced into one end of the tracer optical waveguide, e.g., by Visual Fault Locator, and the light signal is emitted and can be observed from the opposing end, thereby identifying corresponding ends of the tracer optical waveguide, and thus, opposing ends of the connected data cable.

  • Patent number: 8283911
    Abstract: A long range wireless phasing voltmeter determines the phase difference between the time-varying voltage carried on a reference electrical conductor and another, field conductor. The voltage signal from the reference conductor is measured by a reference probe and compared by a first unit in communication with that reference probe to a precision 60 Hz signal generated from a GPS receiver. The phase difference between these, in the form of a nine-bit, audible signal using frequency shift keying to modulate the carrier frequency, is transmitted by the first unit to a second unit perhaps miles away. A receiver in the second unit decodes the signal and uses another precision 60 Hz signal generated from another GPS receiver to re-create a surrogate of the original reference voltage signal. This surrogate signal is forwarded to a meter probe that is measuring the signal on a field conductor. The meter probe can then compare the two signals to determine the phase angle difference between them.
