Self-monitoring high voltage transmission line suspension insulator

Patent ·
OSTI ID:6599285
A high voltage transmission line suspension insulator which monitors its own dielectric integrity is described. A dielectric rod has one larger diameter end fitting attachable to a transmission line and another larger diameter end fitting attachable to a support tower. The rod is enclosed in a dielectric tube which is hermetically sealed to the rod's end fittings such that a fluidtight space is formed between the rod and the tube. A pressurized dielectric liquid or gas is placed within that space. A discoloring dye placed within this space, or a pressure gauge, is used to detect the loss of the pressurized fluid.
