Measuring device for a metal-encapsulated gas-insulated high voltage installation

摘要

The measuring device uses a Rogowski coil (10) contained within an encapsulation sleeve (3) of the metal enclosure. This is used for measuring the current through a current conductor (9), which is enclosed by a measuring electrode (11) for measuring its voltage. The signals from the Rogowski coil and the measuring electrode are fed to an electronic evaluation stage (23,23'), with the current conductor coupled to a current conductive fitting (13) with an insulator (14) fitted to the encapsulation. The conductor may be constructed in two parts, in which the first part incorporates screws arranged in the direction of the main axis.
