Abstract

An apparatus is provided for securing to and collecting power from an electrical conductor, including a current transformer comprising a core and an electrical winding that receives an induced current from magnetic flux generated according to alternating current present on the electrical conductor, and a clamping mechanism that attaches the apparatus to the electrical conductor. According to various aspects, apparatus may include a housing that encloses circuitry for monitoring conditions of the electrical conductor, where the circuitry includes one or more sensors, and wireless communications circuitry.

First claim

What is claimed is:

1. An apparatus for collecting power from an electrical conductor, comprising:
a housing including a cavity that encloses a circuitry that monitors conditions of the electrical conductor;
a plurality of current transformers each comprising a magnetic core that receives an induced magnetic flux generated according to alternating current present on the electrical conductor, each of the plurality of current transformers being secured to a respective side of the housing,
wherein the magnetic core of each current transformer includes a first arm section and a second arm section that are spring biased using one or more springs to remain in a closed position,
wherein the first arm section and the second arm section of each current transformer is at least partially separable at a portion of the current transformer by applying a force against the spring bias at the partially separable portion, and
wherein each of the first arm section and the second arm section of each current transformer includes one half of the magnetic core; and

a clamping mechanism that attaches to the electrical conductor.

2. The apparatus of claim 1 , wherein the circuitry includes one or more sensors and indicators.

3. The apparatus of claim 2 , further comprising:
an energy storage device,
wherein each of the plurality of current transformers further includes an electrical winding that receives an induced current from the induced magnetic flux generated according to alternating current present on the electrical conductor, and
wherein the circuitry further includes a circuit configured to convert the induced current into energy to be stored in the energy storage device for consumption by the one or more sensors and indicators.

4. The apparatus of claim 1 , further comprising at least one clip that secures the first and second arm sections of at least one of the plurality of current transformers in a locked position.

5. The apparatus of claim 1 , wherein the clamping mechanism comprises a wire clamp including clamp arms.

6. An apparatus for collecting power from an electrical conductor, comprising:
a housing including a cavity;
a current transformer comprising a core and a winding that receives an induced current from magnetic flux generated according to alternating current present on the electrical conductor;
a clamping mechanism that attaches to the electrical conductor,
wherein the clamping mechanism includes a securing lever,
wherein the securing lever is adjustable between an open position and a closed position by engaging an eye formed on one end of the securing lever,
wherein in the open position the securing lever is substantially parallel to the electrical conductor and in the closed position the securing lever is substantially perpendicular to the electrical conductor such that the apparatus rests on the electrical conductor at the securing lever and the electrical conductor is disposed between the securing lever and the housing; and

a circuitry disposed within the cavity of the housing that monitors conditions of the electrical conductor, the circuitry including a circuit configured to convert the induced current into energy to be stored in an energy storage device for consumption by one or more sensors and indicators.

7. The apparatus of claim 6 , wherein the current transformer comprises first and second magnetic core sections, the first and second magnetic core sections being separable.

8. The apparatus of claim 7 , wherein the current transformer includes one or more springs to spring bias the first and second magnetic core sections to a closed position.

9. The apparatus of claim 6 , further comprising at least one clip that secures the first and second magnetic core sections of the current transformers in a locked position.

10. The apparatus of claim 6 , wherein the clamping mechanism further comprises a bumper post disposed adjacent the securing lever, and wherein the bumper post is configured to and disposed such that it prevents an over rotation of the securing lever past the closed position.

11. An apparatus for collecting power from an electrical conductor, comprising:
a first current transformer and a second current transformer, each current transformer comprising a first section and a second section, the first and second sections hingedly coupled to each other via a base portion and separable from a tip portion,
wherein each of the first and second current transformers receives an induced current from magnetic flux generated according to alternating current present on the electrical conductor retained in a cavity defined by the first and second sections of each current transformer; and

a housing enclosing circuitry which enables monitoring and sensing of one or more conditions of the electrical conductor via the first and second current transformers, wherein the first current transformer is disposed on a first side of the housing and the second current transformer is disposed on a second side of the housing opposite the first current transformer; and
a securing lever coupled to the housing and disposed adjacent a portion in between the first current transformer and the second transformer,
wherein the securing lever is adjustable between an open position and a closed position by engaging an eye formed on one end of the securing lever,
wherein in the open position the securing lever is substantially parallel to the electrical conductor and in the closed position the securing lever is substantially perpendicular to the electrical conductor.

12. The apparatus of claim 11 , wherein the first and second sections each comprise an angled tip, wherein the angled tips are biased closed by a spring in the base portion and separated when the electrical conductor is pushed therebetween and into the first and second current transformers.

13. The apparatus of claim 11 , wherein the apparatus hangs from the electrical conductor at the securing lever.

14. The apparatus of claim 13 , wherein the housing hangs below the electrical conductor when the apparatus is suspended on the electrical conductor.
