PARTIAL DISCHARGE BEHAVIOUR OF TWO (OR MORE) ADJACENT CAVITIES IN POLYETHYLENE SAMPLES

Michael G. Danikas

   In the present paper, the partial discharge behaviour of two (or more) adjacent cavities in polyethylene samples is investigated. The recorded discharge currents had very steep rise times (in the range of ns). The question as to whether a simultaneous breakdown occurs in both cavities or the breakdown of one cavity causes the breakdown of the other(s) is discussed.

Keywords: partial discharge, enclosed cavities, rise time, apparent charge
