Abstract :
The severity of the effects of contamination on post insulators in four different HVDC converter stations is illustrated by a series of field measurements. The data are analyzed to show the effects of polarity, stress, voltage magnitude, and distribution of contaminant along and around the insulators. Recommendations are made for evaluation of post insulator flashover strength using the clean-fog artificial contamination test
