Patent ID: 8594956

Claim:
An energy harvesting device for harvesting energy from a power line conductor, comprising: a current transformer comprising an electrical winding disposed thereon, the current transformer configured to receive an induced current on the electrical winding via magnetic flux energy generated by alternating current on the power line conductor, wherein the current transformer defines an opening having an axis that is perpendicular to and runs through the center of the opening; a housing comprising a first portion and a second portion, the first portion adjacent to the second portion along the axis, wherein the current transformer is disposed on the first portion; a clamping mechanism comprising clamp arms, each clamp arm being spring biased to maintain the clamp arm in a closed position, wherein the clamping mechanism is disposed on the second portion of the housing; and a circuit electrically coupled to the electrical winding and configured to convert the induced current into electrical energy for consumption by an electrical device.
