ON THE DISCHARGE PHENOMENA BELOW INCEPTION VOLTAGE: FURTHER EXPERIMENTAL RESULTS WITH AIR GAPS

Michael G. Danikas

   The problem of possible insulation damage - due to random discharges - below the inception voltage has not attracted, as a subject of research, much attention worldwide. Indications of possible damage below inception in solid dielectrics already exist. In this paper, we examine the existence of random discharges in small air gaps with a fixed applied voltage. It is concluded that random discharges (in some cases quite numerous) may appear in air gaps even greater than the air gap at which normally breakdown takes place.
