  • Patent number: 9581624
    Abstract: An electric power line monitoring, communication and response system schedules the transmission of packets to occur during voltage zero-crossing intervals when corona is minimized. The transmitters may be located at high voltage hanging directly from the power line conductors along with associated current transformers and voltage sensors. A system of these transmitters distributed throughout the power grid communicate with each other in a data-forward manner to bring complete, real-time current and voltage waveform, device status and fault monitoring information to data aggregation waypoints, such as transmission substations where supervisory control and data acquisition (SCADA) equipment is installed. The power line monitoring data is then transmitted from the data waypoints to a central monitoring and control center, typically using existing SCADA equipment, to provide h detailed power line monitoring data for a large number of data monitoring points distributed throughout the power grid.
