Image intensifier monitoring of power line insulator leakage

Creators

Description

This patent describes a method for detecting incipient flashover of a power line insulator. It comprises: using an image intensifier to observe an electrical insulator in an energized power line, and while observing the insulator, illuminating the electrical insulator with an ultraviolet laser beam, whereby generation of detectable electromagnetic radiation from the insulator in response to the illumination indicates incipient flashover
