Abstract: The present disclosure pertains to systems and methods for low-power optical transceivers. In one embodiment, a low-power optical transceiver may include a microcontroller and an optical receiver and an optical transmitter in communication with and controlled by the microcontroller. The optical receiver may include a photodetector configured to receive a first optical representation of a first signal to be received and to generate an electrical representation of the first signal. An amplifier may amplify the electrical representation of the first signal, and an output in electrical communication with the amplifier may generate an electrical output. The optical transmitter may include a laser diode configured to generate a second optical representation of a second signal to be transmitted. The microcontroller may be configured to control an output power of the laser diode.

Abstract: Systems, devices, and methods are provided for a wireless radio repeater for integration in an electric power distribution system. Such a system may include an electrical measurement device and a wireless radio repeater. The electrical measurement device may be installed on a power line of an electric power distribution system, obtain an electrical measurement of the power line of the electric power distribution system, and transmit a wireless message indicating the electrical measurement. The wireless radio repeater may receive the wireless message from the electrical measurement device and re-transmit the wireless message to a control system of the electric power distribution system or to another wireless radio repeater to assist in sending the wireless message to the control system of the electric power distribution system.

Abstract: A wireless radio repeater includes an antenna configured to receive a message associated with an electric power delivery system. The wireless radio repeater also includes circuitry configured to receive electrical measurement data, identify a condition of the electric power delivery system based on the electrical measurement data, and cause the antenna to re-transmit the message received via the antenna in response to identifying the condition based on the electrical measurement data.

Abstract: The present disclosure pertains to detection of a broken conductor in an electric power system. In one embodiment, a broken conductor detector may be configured to be mounted to an electrical conductor and may comprise a communication subsystem configured to transmit a signal configured to indicate that the conductor is broken. A sensor may determine a plurality of vectors. A processing subsystem may be configured to receive the plurality of vectors from the sensor and to identify when the vector is outside of a range defined by a threshold value. The processing subsystem may determine that the conductor is falling based on the plurality of vectors remaining outside of the threshold for a period of time determined by the timer subsystem. A signal may be transmitted by the communication subsystem to indicate that the conductor is falling.

Abstract: The present disclosure pertains to a line-powered current measurement system to mount to an electrical conductor and related methods. In one embodiment, a system may comprise a current transformer to electrically couple to an electrical conductor and to generate a secondary current proportional to a primary current in the conductor. A power harvesting subsystem may harvest power from the secondary current in a first configuration. A switching subsystem may transition the line-powered current measurement device between the first configuration and a second configuration, in which a current measurement subsystem generates a measurement of the secondary current. The switching subsystem may provide the secondary current to the power harvesting subsystem in the first configuration and may bypasses the power harvesting subsystem in the second configuration. A communication subsystem may transmit the measurement of the secondary current to a receiver device.

Abstract: The present disclosure pertains to systems and methods for reducing startup times of line-mounted fault detectors. A line-mounted fault detector may comprise a power harvesting subsystem and an energy storage subsystem configured to store electrical energy. A fast-start power coupling subsystem may receive power from the energy storage subsystem in a startup state and provide power to a subset of components. A DC-DC converter subsystem may start up after a voltage of the energy storage subsystem exceeds a threshold. A control subsystem may transition the line-mounted fault detector to an operating state once the DC-DC converter has started and may de-energize the fast-start power coupling subsystem. The control system may enable a flow of electrical energy from the DC-DC converter to the fast-start subsystem. A fault detection subsystem in electrical communication with the DC-DC converter subsystem may communicate an indication of a fault via an RF transmitter subsystem.

Abstract: Disclosed herein are a variety of systems and methods for correcting for propagation delay in time signals used in connection with an electric power generation and delivery system. According to various embodiments, a device consistent with the present disclosure may determine an estimated propagation delay between an accurate time source and a receiving device. The propagation delay may be determined based on a variety of transmission parameters including, for example, communication channel type and/or length. A corrected time signal may be generated by advancing a reference incitation such as an “on-time” reference and/or “start-of-second” reference included in the time signal by an amount associated with the propagation delay. The corrected time signal may then be transmitted to the receiving device.
