Long‐term statistics of corona loss of HVDC transmission line

The Journal of Engineering, 2019
Corona loss is one of the electromagnetic environment parameters of high‐voltage direct current (HVDC) transmission lines. So far many countries have carried out researches and measurements on it. In 2008, UHVDC test lines were established in the National Engineering Laboratory for UHV Technology (Kunming) at the altitude about 2100 m.
