<p>A current transformer for use with a long continuous conductor (1) comprises a core (2) having at least two legs (5) extending therefrom to form an air gap (4) through which the continuous conductor may pass. The legs (5) may be plate-like or curved. A secondary winding (3) of the transformer is positioned around the core. The surface area of the legs (5) adjacent the air gap is substantially greater than the cross-sectional area of the core.</p> |
