Inductive voltage transformer

In a metal-clad, high-voltage installation having a metal enclosure at low potential and a conductor for carrying a high potential disposed within the metal enclosure, an inductive voltage transformer disposed between the potentials of the metal enclosure and the conductor, the inductive voltage transformer comprising:

• a first flux-conductive part made of electrically and magnetically-conductive material and electrically connected to the conductor of the installation;
• a high-voltage winding surrounding said first flux-conductive part and having a surface facing away from said flux-conductive part;
• a low-voltage winding arranged at said surface of said high-voltage winding;
• a second flux-conductive part electrically connected to the metal enclosure and made of electrically and magnetically-conductive material, said second flux conducting part being disposed in spaced relation to said first flux-conductive part so as to be adjacent thereto;
• and flux-conductive intermediate means extending between said potentials for connecting said parts together to conjointly define therewith a composite core enclosing said high-voltage and said low-voltage windings therein thereby reducing the stray inductance of said windings, said intermediate means being made of a material that is magnetically conductive while at the same time being electrically insulative thereby preventing a conductor to enclosure fault through said intermediate means during the operation of the high-voltage installation.
