Effective Corona Noise Current Injection on Bundled-Conductor Lines

Injection of noise current from corona sources on bundled subconductors is analyzed. The short-circuit effect of suspension clamps and spacers on the injected currents is determined. It is found that the RI performance of a bundle with insulated subconductors is the same as that of a conventional bundle. A simplified analysis of bundled-conductor lines represented by single-conductor lines is suggested.
