Abstract:

A device and method for sensing current flowing in an electrical conductor. An open loop of flexible magnetically conductive material is positioned to substantially encircle a current carrying conductor. Two ends of the loop overlap to form a flux gap between them. Magnetic flux of the magnetic field associated with the current is concentrated in the flux gap. A Hall Effect transducer mounted in the flux gap senses the magnetic field and hence the current flowing in the conductor.
