要約(英語): Audible noise arising due to corona discharge on overhead transmission line conductors is one of the important factors in the design of the transmission line conductors. Therefore, the audible-noise characteristics of the conductors are often measured using a corona cage.In the corona cage, an electric field distribution is generated around the conductors in much the same state as an actual situation except for in the vicinity of both ends of the conductors. Since the length of the conductors in the corona-cage test is only 30m, it is necessary to convert the measured corona-audible-noise levels to values independent of the length of the conductors and the position of the microphone to predict corona-audible-noise levels from conductors in an actual situation. In the conventional technique, the measured corona-audible-noise levels are converted assuming that the electric field distribution on the conductors is uniform, although this is not actually the case.In this paper, we propose a new technique for converting the measured results considering the electric field distribution on transmission line conductors and confirm the validity of the assumption used in the conventional technique.
