Abstract (en)
A combined current and voltage transformer for high voltages consists of a current transformer of inverse type placed in the transformer head (1) and an inductive voltage transformer with a stack magnetic core (9). The secondary leads (7) of the current transformer are laid by or through the open magnetic core (9) of the voltage transformer, which together with its appertaining secondary winding (11) of the voltage transformer is placed in the vertical axis of the transformer inside an earthed supporting tube (8) and around which is placed the insulation of the voltage transformer (12), which together with the insulation of the current transformer in the area of the head (5) make an unseparably entity. The sections of the primary winding (13) of the voltage transformer are placed vertically inside the supporting insulator (2) around the insulation of the voltage transformer (12). <IMAGE>
