| Abstract: | The influence of conductor surface conditions on corona discharge is of great value to the design and operation of power transmission lines in power system.Six strands of the aged conductors acquired from 500 kV AC transmission lines in northern,central,southern China respectively and two strands of the new conductors China were used.The results of scanning electron microscopy(SEM) and energy-dispersive X-ray analysis(EDX) showed that the morphologies of the aged strands were greatly different from the new ... |
