Electrical breakdown in vacuum
Journal of the Institution of Electrical Engineers, 1953Direct and impulse voltages were applied to an electrode system in a vacuum of the order of 10−5 mm Hg. Of particular interest were the results obtained with a needle-and-sphere system, the breakdown voltage of which was considerably higher than that of a normal sphere-gap with the same electrode spacing, especially when a very fine needle was used ...

Electric breakdown in dielectric liquids [PDF]
Physics in Technology, 1985 Electrical power systems rely on effective insulation. A better understanding of the processes leading to breakdown is essential in improving overall reliability. The authors attempt to explain the breakdown phenomenon in general based on the observations made with dielectric liquids.

Electrical breakdown in vacuum
IEEE Transactions on Electron Devices, 1965Theories and experimental facts of vacuum breakdown are reviewed. Measurements with gap spacings of 0.015 inch indicate little or no variation of breakdown with tube pressure between approximately 10-5and 10-7torr and with frequency of the applied voltage from 0 to 6 Mc/s.

Electrical discharges and breakdown in gases [PDF]
Digest of Literature on Dielectrics Volume 38 1974, 1974 The scope and format of the chapter are similar to those of previous years, the literature being reviewed under the following major headings: Monoenergetic Beam Experiments; Swarm Data; Uniform Field Breakdown; Nonuniform Field Breakdown; Breakdown with High Frequency and Magnetic Fields; Laser-Induced Breakdown; Gas Lasers; and Applications.

The electrical breakdown in vacuum
Applied Scientific Research, Section B, 1961Experiments have been performed in order to get information about the phenomena preceding the electrical breakdown in small vacuum gaps. Most experiments have been made with impulse voltages of different rise times; some complementary results obtained with alternating voltage are also presented. The effect of surface layers on the breakdown voltage and

Electrical breakdown by tracking
Proceedings of the IEE - Part B: Electronic and Communication Engineering, 1962When an electrically stressed insulating material is exposed to conditions which contaminate its surfaces, the tendency for the resultant transient leakage currents to form conducting tracks on insulator surfaces is of recognized importance. This form of failure is known as tracking and the processes leading to its development are very dependent on the

Digest of Literature on Dielectrics Volume 34 1970, 1970
The chapter covers fundamental ionization processes in gases, mobility measurements, breakdown in uniform and nonuniform fields, laser induced breakdown, lightning, and applications of gas breakdown and gaseous insulation. A new section has been added to cover developments in the field of high pressure gas lasers, and the bibliography has been extended

Electrical Breakdown in the Space Environment [PDF]
, 1991 The domain of parameters for breakdown in the space environment involves extreme conditions such as non-uniform field, Nd/(Nd)m ≪ 1 (where N is the density of the background gas, d is the electrode separation, and (Nd)m is the value of Nd at the Paschen minimum), and magnetic field, and in addition, the influence of a weakly ionized background gas.

Electrical breakdown in cryogenic liquids
Journal of Electrostatics, 1979Abstract Both the statistical time lag T s and the formative time lag T f of the breakdown in cryogenic liquids (Liq.Ar, N 2 and He) are evaluated from the Laue plots of the breakdown time lag induced by a voltage pulse having a 100-ns pulse width.
