Abstract :
To research the effect of high altitude on corona performance of UHV DC transmission line, the corona inception voltage gradient of a copper line at different air pressure level from 101 kPa to 61 kPa was measured in a mini corona cage. The results have been compared with calculated results of Peek law and the corona inception voltage gradient correction factor of air pressure was presented.
