Abstract
Apparatus and methods for measuring current flowing through a conductor include a device comprised of a magnetically conductive loop having a plurality of strands and a magnetic field sensor. Each strand has a magnetically conductive material. The strands are configured to pass a magnetic field to a first magnetic field sensor that is positioned adjacent to an end of the first plurality of strands. The plurality of strands may be arranged in various patterns that allow the magnetically conductive loop to be more bendable or flexible than a current-clamp device.
Claims23
A device for measuring electric current flowing through a conductor, the device comprising:
- a magnetically conductive loop that is positionable to surround the conductor, wherein the magnetically conductive loop includes a plurality of strands;
- and
- a magnetic field sensor that is positioned adjacent to an end of the plurality of strands to sense a magnetic field,
- wherein each strand of the plurality of strands comprises a magnetically conductive material, and
- wherein the plurality of strands is configured to pass to the magnetic field sensor a magnetic field that is indicative of an electric current flowing through the conductor.
A method of measuring a current flowing through a conductor, comprising:
- positioning a magnetically conductive loop around the conductor, wherein the magnetically conductive loop includes a plurality of magnetically conductive strands having an end positioned adjacent to a magnetic field sensor;
- and
- passing a magnetic field from the end of a plurality of magnetically conductive strands to the magnetic field sensor, wherein the magnetic field sensed by the magnetic field sensor is indicative of an electric current flowing through the conductor.
