摘要： An electrical current sensing apparatus includes a magnetic flux sensor which may be disposed adjacent to or within an opening in a conductor. The magnetic flux sensor may be disposed adjacent to a corner of the opening around which magnetic flux resulting from a current conducted through the conductor tends to concentrate. The magnetic flux sensor includes a Hall effect device having a flux sensitive surface. In one embodiment, the conductor has a tubular cylindrical side wall with an opening in which the magnetic flux sensor is disposed. In another embodiment, the conductor has a rectangular configuration with an opening in which the magnetic flux sensor is disposed. In another embodiment, the magnetic flux sensor is mounted on the surface of the conductor adjacent to the opening.
