| Abstract: | The research works are summarized based on the Lufeng Natural Contamination Testing Station built up for the Yunnan-Guangdong UHVDC project. The main results include the contamination level evaluation of the future converter station near by, the ESDD ratio between the DC post insulator and common AC post insulators, the accumulated contamination (ESDD and NDD) comparison on the deep rib type insulator under two conditions of on-load DC power and off-load DC power. In addition, the set of natural contamination test equipment developed by China Southern Power Grid is introduced. |
