A sensor unit coupled to a first wire of a power line for measuring power-related parameters of the power line. The sensor unit contains a first capacitor and makes voltage measurements relative to another wire, to which the sensor unit is coupled by a second capacitor. The captors form a voltage divider such that the sensor unit may measure a voltage in a range much lower than the voltage on the power line. Additionally, the capacitive voltage divider yields a voltage that can be used to power the sensor unit, including by charging an energy storage device. The sensor unit may also supply power to other nearby devices, such as other devices that form a mesh sensor network.

Techniques comprising obtaining, using a sensor unit coupled to a power line in a power distribution system, at least one measurement of at least one inertial property of the power line; and detecting at least one condition of the power line at least in part by analyzing the at least one measurement. A sensor unit configured to be coupled to a power line in a power distribution system, the sensor unit comprising an inertial sensor configured to collect at least one measurement of at least one inertial property of the power line.

Power line management system

An optical voltage sensor for measuring voltage on an underground power line or for use in other scenarios in which access to a conductor is available through a blind hole. The optical voltage sensor includes a light modulating member, such as a Pockel's crystal. A reflective, conductive member is positioned at one end of the light modulating member and another conductive member is positioned at an opposed end. A voltage capacitively coupled to the reflective conductive member induces a voltage across the light modulating member, thereby impacting the amount of modulation. A beam of light is directed through the crystal and reflected back out of the crystal, where the amount of modulating can be measured. The amount of modulation indicates a measured voltage, and can be transmitted to a monitoring station where processing can determine the status of the power grid or generate other results based on the measured voltage.

In a method of testing a residential broadband communication network, a residential gateway or set top box (STB) performs one or more single-ended parametric tests of the residential network that runs therebetween. The residential gateway or STB also performs one or more single-ended reflectometry tests of the residential network that runs therebetween. The residential gateway and the STB perform one or more dual-ended tests of the residential network that runs therebetween. The residential gateway dispatches the results of the foregoing tests to either: a device on the residential network, a device of another network that supplies broadband services to the residential network, or an intelligent device coupled to the residential gateway.

A system for testing a conductor of a structure can include a test device connected to the conductor. The test device is configured to test an electrical characteristic of the conductor and to produce a test result based at least in part on the electrical characteristic. A service provider network may be configured to communicate with the test device to initiate a test and/or to obtain the test result. A customer may use a computing device to obtain information regarding the test result, as well as guidance for troubleshooting and resolving a problem detected with the electrical conductor, such as a fault.

A remote telephone testing device (,) includes a transmitter (,), a receiver (,), a controller (,) and a test circuit (,). In response to the receiver (,) receiving a test signal from a test system (,) via a telephone network (,), the controller (,) communicatively isolates telephone equipment (,) of a subscriber (S) from the telephone network (,) and connects the test circuit (,) to the telephone equipment (,). The test circuit (,) tests the telephone equipment (,) and conveys one or more results of such test to the controller (,) which relays the one or more results to the test system (,) via the transmitter (,). When testing is complete, the telephone equipment (,) is isolated from the test circuit (,) and is communicatively connected to the telephone network (,).
