Abstract: Ahetract -The contamination severity on post insulators in four different HVDC converter stations is illustrated by a series of field measurements. The data are analyzed to show the effect of polarity. stress, voltage magnitude and distribution of contaminant along and around the insulators. Recomendations are made for evaluation of post insulator flashover strength using the clean fog artificial contamination test. I "Flashovers have occurred on outdoor surface insulation in HVDC converter stations not only …
