ABSTRACT:
A clamp-on magnetic sensor includes a U-bar first magnetic core section and a straight magnetic core section that integrally fit together so that the straight magnetic core section is held in place by the U-bar. The compression and the mating of the surfaces to the U-bar and the straight magnetic core section provide superior response to sensed AC current.
