摘要： A split core current sensor a core subdivided into a first core section and a second core section, each of which have a first end and a second end. The first core section and the second core section are spaced apart by a gap. The sensor also includes a plurality of coil windings disposed about the core. A first coil winding is disposed proximate to the first end of the first core section; a second coil winding is disposed proximate to the second end of the first core section; a third coil winding is disposed proximate to the first end of the second core section; and a fourth coil winding is disposed proximate to a second end of the second core section. Each of the first core section and the second core section include a central portion disposed between the first and second ends that is free of coil windings.

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.

摘要： A power harvesting device is provided that may supply low voltage power to operate devices in remote locations. The power harvesting device may be connected to a medium to high voltage power line. First and second capacitors divide the voltage to a lower voltage sufficient to power a device, such as a monitoring device. The power harvesting device and monitoring device may be connected to an electric tower with the power harvesting device being connected to a power line supported by the tower.
