    摘要: A current transforming harvester ("CTH") is capable of producing power from a conductor on a preexisting power grid without alteration of the conductor or the preexisting power grid. The CTH includes a current transformer ("CT") that captures energy via magnetic flux from the conductor. The CT is substantially circular and includes two halves called a "split core," which allow the CT to easily attach to the conductor without opening the circuit in which the conductor operates. A clamping mechanism of the CTH may secure the CTH to the conductor via a pair of spring-biased clamp pads. The CTH includes circuitry that converts the magnetic flux energy captured by the CT into electrical energy suitable for consumption by an electrical device.
