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.

Abstract: The present disclosure relates to an interleaved, static time division multiple access (TDMA) for communicating in a power delivery system. For example, an access point may communicate with a plurality of electronic devices in the power delivery system. The access point may send a first signal indicating a first poll to a first group of devices in the power delivery system to allow the first group of devices to communicate data to the access point during assigned time slots of the first group of devices. The access point may send a second signal indicating a second poll to a second group of devices, separate from the first group of devices, in the power delivery system to allow the second group of devices to communicate data to the access point during assigned time slots following the second poll.
