Various Pollutions of Power Line Insulators
This paper deals with all types of pollutions for power line insulators. In many different references including IEEE standards and various articles, a list of different types of pollutions are introduced. But those lists are not complete and other cases should be added to them. In this paper, all parts of an insulator are introduced and different types of insulator pollutions and the reasons behind existence of these 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 this 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 to choose a suitable fluid with low cost, significant clearing feature and desirable for environmental applications.
