Partial discharges, potential step, solid dielectric.
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. The outbreak of partial discharges above a threshold electric field according to the above combination may come as the result of impact ionization and affects the dielectric aging procedure.
