Abstract
In liquid hydrocarbon, at short electrode distance, the negative needle indicates lower strength than that of positive needle and it reverses at longer electrode distance. The critical distance of this polarity reversal is very short for liquids with large electron mobility like neopentane. In perfluorocarbon liquids, the difference of breakdown voltage for both polarities is much less than that of hydrocarbon liquids. In liq.N 2, the polarity effect of breakdown is similar to that of hydrocarbons and strongly dependent on pulse width, applied pressure. The polarity effect in liq.He is completely different from other liquids and due to the unique behaviour of electrons in liq.He. The polarity effect in liq.Ne is similar to liq.He. These polarity effects in various liquids seem to have some correlation with the mobility in these liquids and are discussed in terms of bubble process and electronic processes like streamer.
