ABSTRACT Disclosed is measuring equipment with an auxiliary electrode for a gas-insulated, enclosed high-voltage power station. The measuring equipment is inserted into a projection of an enclosure. Its auxiliary electrode forms, together with an inner conductor, a high-end voltage capacitor of a capacitive voltage divider and is connected to the enclosure by means of an under- voltage capacitor. A test connector is guided in a gas-tight arrangement out of the projection and connected to an indicator or measuring instrument. To also detect high-frequency transient phenomena, the undervoltage capacitor comprises two cones fitted inside one another with a solid dielectric between them. A terminating resistor, which is connected to the-inner conductor of a gas-tight coaxial plug, is disposed in the inner cone. The terminating resistor is matched to the characteristic impedance of the coaxial plug and that of the test connector. The measuring equipment with the auxiliary electrode can be inserted into tubular gas connections in the enclosure of a high-voltage power station, particularly, compressed gas-insulated, enclosed high-voltage switching stations.
