Abstract
An integrated field and laboratory study was conducted to investigate the mechanism of flashover of contaminated insulators under HVDC conditions. The discovery of the clean-zone phenomenon and a theory of its formation, a method to predict insulator performance in any location by knowing the composition of contaminants gathered in the area, and the effects of weather on insulator performance are discussed. The work on the voltage distribution along a string of insulators led to the use of internal grading to improve the performance of the insulator string. Refs.
