Abstract	Abstract: The lightning impulse flashover voltage on clean and polluted cap and pin insulators under high humidity conditions were measured. It was shown that the negative flashover voltage of non-uniformly polluted insulators is about 15 % lower than the positive one. Bigger difference of over 25 % was found on a model insulator. The electrical strength of disc insulators lightly polluted on the upper part of the shed and heavily polluted under shed can be twice lower than that of clean insulators. 1.
