Corona Studies for Biploar HVDC Transmission at Voltages Between ±600 kV AND ±1200 kV PART 2: Special Biploar Line, Bipolar Cage and Bus Studies

Some special aspects of the corona performance of bipolar HVDC transmission lines, as well as basic results on the corona performance-of bipolar bus configurations, are presented in this paper. In the special bipolar line study, the influence of the line parameters, namely the pole spacing and the conductor height, on the corona performance of bipolar lines is investigated. Results are also presented on the feasibility of using test cages for bipolar corona studies of conductor bundles. The bipolar bus study presents the results of corona performance characteristics of bus configurations required for bipolar HVDC stations in the voltage range of ±600 kV to ±1200 kV.
