Abstract
The invention relates to a current transformer for a high-tension installation, said transformer including a primary winding, a secondary winding and a magnetic circuit, said primary winding including a primary turn suspended coaxial inner and outer conductors in an insulation chamber which contains a dielectric fluid. The secondary winding (28) and the magnetic circuit (27) are disposed around the primary turn (6) on the outside of the chamber. Electrical continuity of the insulation chamber past an insulating seal (24) therein is provided by a jumper (29) which passes round the outside of the secondary winding and the magnetic circuit. The invention applies in particular to very high tension installations.
