Radio Noise and Corona Loss Results from Project EHV

Fair-and foul-weather corona loss and radio noise data from the Project EHV line are presented. Insulator loss and the dependence of corona loss on load current are discussed. Corona and radio noise data were logged continuously from three configurations tested at 500 kv and another at 700 kv and analyzed with a computer. They provide a basis for predicting line performance. The radio noise measurements from the test line are correlated with long-line performance.
