ABSTRACT:
A method for detecting incipient flashover of power line insulators by use of an image intensifier to detect electromagnetic radiation generated by electrical leakage. To improve detection sensitivity, a stimulus such as ultraviolet radiation or an externally applied RF pulse is used to momentarily increase insulator leakage to generate detectable electrical leakage at contaminated insulators.
