The effect of surface roughness on corona-generated electromagnetic interference for long-term operating conductors


This paper presents a research of the surface roughness effects on corona-generated electromagnetic interference of long-term operating conductors. The detailed surface morphologies and roughness of typical long-term operating conductors were measured and analyzed. The radio noise measurement system primarily based on the corona cage was discussed and the particular radio noise generated by the conductor within the measured cage was obtained, primarily based on the parameters of the corona cage and also the measured data. The radio noise tests were meted out below both dry and wet conditions. Under two types of conditions, the corona intensity was higher on the long-term operating conductors contrasted to the new conductors as a results of the anomalistic surfaces of the long-term operating conductors. The rate of decrease of corona inception voltages between the long-term operating conductors and new conductors was discovered to extend with the raise of surface roughness degree Ra in linear relationship. Approximate linear relation was additionally discovered between the averaged radio noise deviation and Ra. The rate of decrease of corona inception voltages underneath wet conditions was slightly higher (regarding 1percent) than that below dry conditions. The distinction between the radio noise of long-term operating conductors which of new conductors was larger (1.three dB) below wet conditions compared to dry conditions.
