Breakdown voltage characteristic of a pseudospark device

Physics of Fluids B: Plasma Physics, 1992
The breakdown voltage of a pseudospark device is measured for a wide range of gas pressure and anode–cathode gap distance. The data are analyzed by least-squares-fit methods, and the breakdown voltage is expressed by an empirical function of the gas pressure and the anode–cathode gap distance. It is found that the breakdown voltage is a function of p2d,

AC breakdown characteristics of epoxy nanocomposites

IEEE Transactions on Dielectrics and Electrical Insulation, 2011
Experiments were conducted to measure the ac breakdown strength of epoxy alumina nanocomposites with different filler loadings of 0.1, 1 and 5 wt%. The experiments were performed as per the ASTM D 149 standard on samples of thickness 0.5 mm, 1 mm and 3 mm in order to study the effect of thickness on the ac breakdown strength of epoxy nanocomposites.

Breakdown characteristics of water walled arcs

Journal of Physics D: Applied Physics, 1988
The breakdown voltage of a high-pressure argon arc is increased by about 80% if water is present in the vessel, and is further increased if the discharge is forced close to the water surface by a metal conductor outside the arc chamber.

Generalized breakdown voltage characteristic of the pseudospark

Applied Physics Letters, 1994
A simple empirical scaling law is determined for the pseudospark breakdown voltage characteristic that includes the effect of the cavity dimension. It is found that the breakdown voltage characteristic has two distinctive regimes: the breakdown voltage is a function of the product of the gas pressure and the anode–cathode distance pd and a function of ...

Characteristics of laser induced gas breakdown

SPIE Proceedings, 2003
We report characteristics of laser induced gas breakdown by changing wavelengths, gas media as well as controlling energies. Pulsed YAG laser beam was focused into the gas chamber in order to study breakdown thresholds and laser transmission through produced plasmas.

Air Breakdown Characteristics at High Altitudes

51st AIAA Aerospace Sciences Meeting including the New Horizons Forum and Aerospace Exposition, 2013
Present investigations have been devoted to analysis of electron ionization and elimination processes at early stages of electric discharge development at altitudes 0$100 km. In the report we consider processes of ionization in the external field and due to background ionization, as well as of attachment, detachment of electrons in collisions with ...

Breakdown Characteristics of Moving Transformer Oil

IEEE Transactions on Power Apparatus and Systems, 1981
As a result of investigating breakdown characteristics of moving oil, it has become clear that the breakdown voltage of ac and dc for moving oil is higher than that for stationary oil by 10-15 % at a moving velocity of 5 cm/s region; the former voltage becomes almost equal to the latter voltage in the region of 25 cm/s, and the former is reduced to ...

Characteristics of Edge Breakdowns on Teflon Samples

IEEE Transactions on Nuclear Science, 1980
Geosynchronous satellites have been observed to exhibit anomalous behavior attributable to electrical discharges resulting from differential charging of satellite surfaces by energetic electrons. A program has been undertaken to study the characteristics of electrical discharges induced on silverbacked Teflon samples irradiated by a monoenergetic beam ...

Breakdown characteristics of air in the lower atmosphere

Moscow University Physics Bulletin, 2011
This study is devoted to an analysis of the ionization and loss of electrons at early stages of discharge development in air at an altitude of 0–12 km. Ionization in an external electric field and background ionization, electron attachment and detachment from atomic and molecular oxygen, charge exchange, and negative ion conversion are considered.
