ABSTRACT:
A current transformer having at least one ring-shaped core with a secondary winding mounted thereon, and a primary conductor, located within its casing. An inner tube is provided between the ring-shaped core and the primary conductor, one end of the tube being electrically connected to the casing and its other parts electrically insulated therefrom. A cylindrical, electrically conductive screening shield at least partially overlaps the inner tube and is electrically connected to the casing on the side of the ring-shaped core which is distal from the electrical connection between the casing and the inner tube, while the other parts of the shield are electrically insulated from the casing. This overlap forms a short-circuit loop for any steep progressing wave which is generated when switching on a potential-free part of the circuitry, or when due to an interruption, a small capacitive current breaks off. The short-circuit loop thus prevents the generation of high inductive voltages at the secondary leads of the current transformer. The overlap also enables a steep progressing wave to progress without reflection and without capacitively influencing the potential of the secondary winding.
