Abstract
Abstract In the disclosed fault detector, a casing has a u-shaped portion for receiving a cable and a portion extending from the u-shaped portion. A screw is mounted on said portion. A pressure device is mounted on the end of the screw and directed toward the u-shaped portion for holding the cable in the u-shaped portion. A magnetic lamination passes through the u-shaped portion. The pressure device is made of a magnetic material and a coil surrounds said laminations.
