Radio noise, audible noise, and corona loss quantities dependent only on the corona phenomena at the conductor surface were determined by means of tests on conductors in cages. These quantities were then utilized to predetermine radio noise, audible noise, and corona loss for typical lines under rain. The dependence on diameter and number of subconductors was investigated. Using these data, the noise and loss characteristics of representative UHV transmission lines were plotted.
