Abstract :
Experimental measurements of the effect of mist formation in vapor-mist dielectrics on impulse breakdown are presented. The water breakdown voltages are shown to increase as the temperature falls to the boiling point. This is an effect of the mist formation. The mist formation is also shown for benzene, hexane, ethyl alcohol, methyl alcohol, Freon R-11, R-113, R-11-R-113 mixture, R-113-R-114 mixture, and R-113-R-12 mixture mist. The electrical strength of the mist depends on the mass increase of clusters
