摘要：
This paper presents the effects of several environmental parameters such as ice weight, atmospheric pressure and pollution severity on the flashover performance of two types of short string suspension insulators and short post insulator. The relationship between the critical flashover voltage of the insulators and insulator profile, amount of ice built up, pollution severity and atmospheric pressure was determined. Moreover, the mathematical expression of minimum flashover voltage of a short string of the suspension insulator units was given. The results obtained are helpful for the insulation design of transmission lines located at icing and high altitudes regions.
