In an assembly consisting of a cylindrical core and a secondary winding wound around the core, a cylindrical magnetic shielding member is interposed between the primary conductor inserted into the assembly and the assembly, the shield The member is formed by winding a thin plate of ferromagnetic material into a cylindrical shape,
A zero-phase current transformer characterized in that a cylindrical member having a cut is fitted inside the shield member so that the elasticity of the cylindrical member presses the shield member against the inner circumferential surface of the assembly.
