| Abstract: | Pollution classification for the external insulation of transmission lines directly affects system security.The saturated equal salt deposit density(ESDD) and the non-soluble deposit density(NSDD) of the double-umbrella type insulator in Jiangsu Power Grid are analyzed,and the saturation coefficient,the asymmetry coefficient,and the NSDD/ESDD ratio are obtained.The site pollution severity(SPS) of typical environments can be identified through measurement of saturated ESDD and NSDD.Methods for modifying the pollution plot of Jiangsu Power Grid are also proposed. |
