The occurrence of dry-band arcs on outdoor composite insulators can degrade the polymeric materials¿ surface and ultimately may lead to insulator failure. The degradation processes are generally considered as aging effects occurring over long periods of time, from years to decades. In this paper, it is shown that if a stable dryband arc is physically compressed in length by external forces, such as electrolyte deformation due to wind or gravity, the arcing activities will become more severe… CONTINUE READING
