EXTERNAL PARTIAL DISCHARGES OF PERTINAX IN AIR

摘要

In this work, high voltage pulses of the form 1.2/50μs were applied on a metal tip-solid dielectric- metal plate combination in the air. The recording of partial discharges in air is a difficult process because the molecules of gasses are volatile and agile. Furthermore, the measurement of the inception time and the duration of potential steps is a difficult process too, because partial discharges are exceptionally short phenomena.
