Abstract
For investigating the flashover characteristics of contaminated-insulator of transmission line in service when exposed to lightning strike
this paper presents test circuit and method which is under lightning impulse voltage superimposed on power frequency voltage. Based on lots of tests
the relation between the flashover voltage of artificial contaminated insulator and the ESDD (equivalent salt deposit density) is investigated and analyzed.
