Abstract :
In the paper is presented a smmary of cage measurements of the radio interference, the audible noise, and the corona losses for a large number of conductors and conductor bundles. The analysis of the test results obtained also leads to the establisment of a theoretical method of predicting the corona performance of conductor bundles, based on experimental data obtained with single conductors and taking into account the actual distribution of the field strength at the surface of individual sub-conductors in the bundle. Some cases of practical interest are discussed with reference to the effect of conductor aging and the asymmetry of the bundle configuration. Application of the theoretical method to the prediction of the corona performance of long three-phase lines, taking the actual field distributions at the center and outer phase conductors into account, is also discussed.
