Metkod of Evaluating Corona Noise Generation from Measurements on Skort Test Lines

The background and underlying assumptions of modern analyses applied to corona noise are reviewed. A method is proposed to compute the noise current generated per unit (pu)* length of conductor from the quasi-peak (QP) value of the field intensity, measured under the phase conductors in the center of an open-ended test line. In this method, measurements are taken at frequencies corresponding to the minima of standing waves, the minima being insignificantly affected by the line attenuation. A numerical example is a case of 1/2-mile horizontal test line.
