Modeling of Polluted High Voltage Insulators

Abstract

High voltage insulators play a very important role in the transmission of power from generation to the consumer end, and in protecting the supporting towers from the high voltage lines as well as it also prevents the flashover due to the sudden rise of voltage and due to other causal factors. In this paper we have analyzed the effects of pollution on the insulator on the critical flashover voltage. Particularly, we have achieved our result by energy analysis of the insulator and the line supplying the energy. Some modification as per the requirement is done from the account of the value of constants such as 'A' the arc constant 'n' the arc index and 'K' a constant multiplied before 'R p ' the resistance of the polluted layer. Overall a new equation of flashover voltage is achieved which differs from the model [1] by some factor i.e., constant.
