High-voltage bushing for a high-voltage system

Abstract

High-voltage bushing (1) for passing an electrical conductor (2) through a housing of a high-voltage system, comprising an insulating body (3) through which the conductor (2) is guided, a mounting flange (4) for attaching the high-voltage bushing (1) to an outer wall (5) of the housing (3), at least one electrically conductive control electrode (6) arranged in the insulating body (2), wherein the control electrode (6) is arranged substantially concentrically around the conductor (3), and wherein an earthing terminal (7) connected to the control electrode (6) is provided in order to ground the control electrode (6), wherein an electrically conductive measuring electrode (8) is provided in the insulating body (3), wherein a capacitive tap (9) connected to the measuring electrode (8) and extending out of the insulating body (3) is provided, and wherein the measuring electrode (8) is arranged substantially concentrically around the conductor (2).and wherein the control electrode (7) is arranged substantially concentrically around the measuring electrode (8) and substantially completely surrounds it.
