Abstract

A high-voltage measurement device for an electrical high-voltage switchboard plant having an measurement electrode built into an encapsulating housing, as well as an electrical conductor which conducts a measurement signal provided by the measurement electrode, connected with the electrode, and passed through the wall of the encapsulating housing in insulated manner. To protect operating personnel from high voltage which occurs at the conductor, the conductor is grounded by metal springs outside the encapsulating housing. These metal springs can be lifted up from the conductor if necessary, by means of activation elements. This is done, for example, by setting a switchboard housing onto a measurement housing which surrounds the conductor. If the switchboard housing is removed, the conductor is automatically grounded again by the metal springs. This high-voltage measurement device can be used for all types of gas-insulated high-voltage switchboard plants.
