Investigation of the corona performance of conductor bundles for 800-kV transmission

Abstract
An investigation of the corona performance of several different conductor bundles for 765/800-kV transmission lines was carried out under a program jointly sponsored by Consumers Power Company and The Detroit Edison Company. The results of tests, carried out on single-phase bundles of 3, 4, 5, and 6 conductors, are presented in the form of generation quantities of audible noise, radio interference, and corona loss. The influence of bundle asymmetry and conductor surface condition on generation quantities was investigated. A comparison of the expected performance of 3- phase transmission lines using several of the tested bundles is given.
