Pre-breakdown phase of coplanar dielectric barrier discharge in helium
The European Physical Journal Applied Physics, 2016Coplanar barrier discharge in single-pair electrode configuration was used to study the formation of helium diffuse mode discharge. Transition from Townsend avalanching to the cathode and anode directed ionization waves was documented by high-speed camera imaging.

Dielectric breakdown and partial discharge in BaTiO/sub 3/ ceramics
Proceedings of the 3rd International Conference on Conduction and Breakdown in Solid Dielectrics, 2003The possibility of a correlation between partial discharge characteristics, breakdown strength, and microstructure of the ferroelectric ceramics is investigated. Breakdown field and partial discharge inception field were measured for pure BaTiO/sub 3/ ceramics with different pore size distributions.

Dielectric barrier discharges: Pulsed breakdown, electrical characterization and Chemistry
2013 19th IEEE Pulsed Power Conference (PPC), 2013The application of atmospheric pressure discharges in new fields like environmental protection, surface treatment or life-sciences requires a profound knowledge on the plasma parameters and properties. This includes the characterization of the breakdown processes triggering plasma chemistry, the proper determination of the electrical parameters and the

Effects of the Dielectric Layer on a Planar and a Coplanar Discharge Breakdown
Japanese Journal of Applied Physics, 1998There are two influences of a dielectric layer on the breakdown in Paschen's law. The potential difference at the dielectric layer itself enhances the minimum value of firing voltage, while the strong field in the discharge space with a large dielectric constant reduces the firing voltage in a high pressure range.

IEEE Transactions on Electrical Insulation, 1977
An investigation of internal discharge phenomena in artificial air-filled cavities in impregnated-paper, polyethylene, and polypropylene over a temperature range from 90 to 343 K is described. The technique used for the detection and measurement of internal discharges has a high resolution and sensitivity, and incorporates a multi-channel, pulse-height

The deterioration and breakdown of dielectrics resulting from internal discharges
Journal of the Institution of Electrical Engineers, 1951The deterioration of polythene and other dielectrics, when exposed to internal discharges, has been examined under controlled conditions. The discharge-inception voltage and the magnitude and energy of individual discharges have been determined, and the location and number of discharges in voids of different dimensions have been studied, by ...

The breakdown threshold of dielectric barrier discharges in piezoelectric polymer foams
2010 Annual Report Conference on Electrical Insulation and Dielectic Phenomena, 2010The piezoelectric activity of charged cellular foams (so-called ferroelectrets) is compared against simulations based on a multi-layer electromechanical model and Townsend's model of Paschen breakdown, with the distribution of void heights determined from scanning electron micrographs.
