CORONA PERFORMANCES OF CONDUCTOR BUNDLES MEASURED IN CORONA CAGES AND ITS APPLICATION

, , and .
(1981)

Abstract

Corona performances of various conductor bundles suitable for EHV and UHV transmission lines were tested in the EHV and the UHV corona cages at the Shiobara laboratory. Audible noise, radio interference and television interference were measured during natural rain and under artificial rain condition. Audible noise and radio interference levels calculated by using these results were well agreed with the long-term test results of EHV test lines. Culculated hum noise level was, however, much higher than the test line result. This could be attributed to the differences in conductor againg and rain rate.
