摘要： Devices, systems, and methods for measurement of parameters of electric power transmission lines can improve electric power usage, while wireless circuitry can provide communication from field-located devices. Connection to draw electrical power from the transmission line can be distinct from connection to sense line parameters.

摘要： Unique systems, methods, techniques and apparatuses of a power line measurement device are disclosed. One exemplary embodiment is a measurement device comprising a measurement device structured to at least partially surround a segment of a power distribution line, the measurement device including a winding portion spaced apart from the segment of the power distribution line structured to receive magnetic flux from the power distribution line and to output data corresponding to a current flowing through the power distribution line; and a magnetic shield spaced apart from the measurement device and positioned radially outward from the winding portion relative to the segment of the power distribution line, the magnetic shield comprising a first section and a second section coupled to the first section at an obtuse angle, the magnetic shield being structured to reduce an amount of external flux from being received with the measurement device.
