Various Pollutions of Power Line Insulators
This paper deals with all types of pollutions occurring in electric power line insulators. In many different references including IEEE standards and various articles, a list of different types of pollutions have been introduced. However, the mentioned list is not complete and some other cases should also be added to that list. In this paper, all parts of an insulator are introduced and different types of insulator pollutions and the reasons behind existence of such pollutants are identified as well. Furthermore, appropriate pictures for various types of insulator pollutions are provided to give an accurate understanding of these pollutions for future works, and also make us able to adopt preventive measures according to the type of pollution in order to reduce or remove the pollution resources of insulators and other system equipment. Moreover, with the aim of washing polluted insulators, these pictures help us to choose a suitable fluid with low costs, significant clearing feature and the one that is desirable for environmental applications.
