With the obvious change of global climate characteristics and rapid development of industrial economy, the number of faults on grid equipment in Jiangsu Power Grid caused by meteorological disasters is showing an in-creasing trend year by year,especially the contamination flashover faults and wind deflection faults. On the basis of extensive investigation,this paper presents the fault characteristics of power grid equipment under wind, thunder-storm,haze or ice.And furthermore it pinpoints the main meteorological elements and the related influence law.Com-bining with the existing operation experience and prevention measures,this paper gives the overall defense advice for power grid against meteorological disasters, including improved design and plan of power grid equipment, employment of new technology,meteorological disaster monitoring and warning system.The results above can provide important reference for the designing, maintaining and fault prevention of power grids with similar meteorological conditions.
