1. A measuring device for a metal-enclosed, gas-insulated high-voltage installation having at least one Rogovski coil, which is arranged in an enclosure tube, filled with insulating gas, of the metal enclosure and serves to detect the current in a current-carrying conductor led through the enclosure tube, having at least one measuring electrode, which surrounds the conductor and serves to detect the voltage of the conductor, and having at least one electronic evaluation device, which processes output signals of the Rogovski coil and the measuring electrode, wherein the current conductor is rigidly connected to a current-conducting cast armature of an insulator fastened to the enclosure tube.
