A new approach in modeling AC flashover voltage for polluted insulator

Contamination-driven insulator failure is a problem that incessantly plagues distribution system. It erodes power quality and diminishes system reliability. Research on insulator pollution is directed primarily to understand the physics of the growth of discharge and to develop a mathematical model,...
