A REVIEW OF EXPERIMENTAL STUDY AND PERFORMANCE OF INSULATOR USING VARIOUS COATING MATERIALS

Pollution flashover is a critical problem which affects the safety of operation of power system. In order to prevent pollution flashover accidents of outdoor insulation devices, a series of anti-pollution coatings got application. Different alternatives are used to improve the behavior of the electrical insulation used in transmission lines and thus reduce or prevent the transmission line outages caused by pollution.
