Abstract

Corona and electric field effects are important aspects to be considered in the design of HVDC transmission lines. The results of an extensive IREQ-EPRI study on the corona performance characteristics of transmission lines in the range of ±600 kV to ± 1200 kV are presented in this paper. The longterm corona performance characteristics of three conductor bundles, chosen for use in this voltage range, are discussed. Subjective studies of RI and psychoacoustic studies of AN, required to establish proper design criteria for these two parameters, are also described. Finally, some investigations on the measurement of electric field and ion current distributions under DC lines, as well as of electric induction effects on objects and people located under the lines, are reported.
