A current sensor has a secondary coil 14 disposed on a straight portion of a magnetic core member 12 whose ends are bent round and electrically and magnetically joined, for example by welding at 30. Alternatively the ends may be joined by a crimped-on magnetic sleeve, or bound together by magnetic wire. The arrangement may be disposed in a casing 32 filled with a potting compound. A single turn primary winding may link the core. <IMAGE> |
