Breakdown Threshold of Dielectric Barrier Discharges in Ferroelectrets: Where Paschen's Law Fails

open access: yesIEEE Transactions on Dielectrics and Electrical Insulation, 2011
The 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.

Electric conduction breakdown and partial discharges in dielectric fluids. I. Partial discharges

open access: yes[1991] Proceedings of the 3rd International Conference on Properties and Applications of Dielectric Materials, 2002
Some studies have suggested that there may exist a relationship between conduction and electrical breakdown. Before such a correlation between these phenomena and partial discharges (PDs) can be investigated, it is necessary to produce reproducible PD data.

Computer Modeling of Electrical Breakdown in a Pulsed Dielectric Barrier Discharge in Xenon

IEEE Transactions on Plasma Science, 2002
Computer modeling of the plasma kinetics in a short-pulse excited dielectric barrier discharge in Xe has been used to simulate the spatial-temporal evolution of the homogeneous plasma during the electrical breakdown phase. The breakdown coincides with the development of a streamer-like ionization wavefront propagating toward the cathode at /spl sim/10 ...

Breakdown Characteristics of Atmospheric Dielectric Barrier Discharge in Gas Flow Condition

Physics of Plasmas, 2018
Experimental investigations of the breakdown characteristics of plate-to-plate dielectric barrier discharge excited by an AC source at different gas flow conditions are carried out. The ignition voltage for the appearance of the very first discharge filament and the breakdown voltage in each discharge half cycle in continuous operation are examined. As

Charge-discharge breakdown of dielectric ceramic

Proceedings of the 6th International Conference on Properties and Applications of Dielectric Materials (Cat. No.00CH36347), 2002
The breakdown behavior of high-voltage dielectric ceramics experiencing long-time charge and discharge cycles is not the same as its short-time breakdown behavior. In our study, it was found that there are about four types of breakdown and various factors such as test voltage, ceramic Curie temperature, epoxy encapsulation, and interface treatments ...
