Abstract: Systems, methods, and apparatuses for one-way communications are disclosed. A system includes a transmitter, a first receiver, and a second receiver. A transmitter transmits one or more messages on one or more channels according to a predetermined, pseudo-random channel hopping protocol. The receivers receive said transmissions according to the order of the pseudo-random channel hopping protocol. Methods for re-syncing the one-way system in the event of a power loss or other event causing desynchronization. Default waiting channels are established for the receivers once a certain number of channel detection periods according to the one-way communication protocol result in no detected signals.

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: 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 system for monitoring a voltage of a conductor of an electric power delivery system after automatic voltage sensor calibration. The system includes a sensor for capacitive coupling with an access point. The system includes an IED in electrical communication with the sensor to obtain signals therefrom. The IED may be configured to automatically calibrate to accommodate the signals from the conductor obtained using the sensor. The IED may provide an output depending on the determined voltage on the conductor.
