Granted: 2013-05-28
Abstract: A composite insulator containing means for providing early warning of impending failure due to stress corrosion cracking, flashunder, or destruction of the rod by discharge activity conditions is described. A composite insulator comprising a fiberglass rod surrounded by a polymer housing and fitted with metal end fittings on either end of the rod is doped with a dye-based chemical dopant. The dopant is located around the vicinity of the outer surface of the fiberglass rod. The dopant is formulated to possess migration and diffusion characteristics correlating to those of water, and to be inert in dry conditions and compatible with the insulator components. Deposits of activated dopant on the outer surface of the insulator can be detected upon imaging of the outer surface of the insulator by appropriate imaging instruments or the naked eye.
