ABSTRACT:
A measuring transformer for a fully-insulated, metal-clad, high-voltage installation equipped with a metal outer tube containing a high-voltage conductor includes a tube member arranged within the metal outer tube in surrounding relation to the high-voltage conductor. The tube member constitutes a surface-type electrode an conjointly defines with the high-voltage conductor a high-voltage capacitor. A low-voltage capacitor is connected to the high-voltage capacitor so as to conjointly define therewith a capacitive voltage divider. A transformer core unit including an iron core and a transformer winding system mounted on the iron core is also provided. The transformer core unit is arranged on the outer surface of the tube member whereby the tube member carries the transformer core unit inside the metal outer tube of the high-voltage installation.
