| Abstract: | The corona loss in HVDC transmission lines and relative parameters such as radio interference, audible noise, resultant electric field and ion current have become a key for design and operation of the power system. Measurements of electromagnetic environment parameters with the ± 800 kV DC transmission line in the National Engineering Laboratory (at the altitude of 2 100 m for UHV Engineering Technology, Kunming, China are performed. The Principle of measurement system and device is introduced. The corona and relative parameters are studied under defferent atmospheric condition. It is concluded that the atmospheric condition at high altitude has obvious effect on the electromagnetic environment. |
