Abstract
The accumulation of salt contamination could be the source of electrical accident. The degree of contamination on outdoor insulator is represented by ESDD(equivalent salt deposit density). The salt is transported by the wind to the outdoor insulator and cleaned by the rain. So, we can estimate the relation between climatic data and ESDD by using the multiple regression method. The results of pre-study presented the high relation coefficient(0.874). But these results couldn't apply to another period So, this paper improves above problem by mathematical process of climatic data The main method is accumulation of passed climatic data and conversion of the rainfall by the wind. Then, we confirmed the increasement of relation coefficient(0.898).
