Effect of total voltage on breakdown in vacuum

Electrical Engineering, 1935
The results of a series of high voltage breakdown tests between metal electrodes in high vacuum are reviewed, with consideration of the observed inverse relation between cathode gradient at breakdown and gap length. This leads to the conclusion that the current that flows between electrodes as the conditions for high voltage breakdown are approached ...

An apparatus for automatic breakdown-voltage measurement [PDF]

Journal of Physics E: Scientific Instruments, 1973
Nonrepeatability in measured values of the static breakdown voltage Vs of uniform-field high-pressure gas-discharge gaps necessitates a large number of measurements to be made in order to construct meaningful Vs distribution curves. An apparatus has been constructed which is capable of automatic measurement and recording of breakdown voltage data. This

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 ...

Thickness dependence of dielectric breakdown voltage

Thin Solid Films, 1986
Abstract Some thought was given to the electric breakdown mechanism of anodic aluminum oxide. The foundation of the proposed void erosion model lies in microstructural observation and channel propagation physics. A statistical analysis of the scatter in breakdown voltage data is presented.

Breakdown voltages of ion-implanted junctions

Journal of Applied Physics, 1985
In this paper an analytic analysis of the breakdown voltage of an ion-implanted junction is presented. A joined half-Gaussian distribution of the implanted ions is used, since it gives better description of the impurity profiles. The results are based on a closed-form solution of Poisson’s equation in the depletion region.

The Breakdown Voltage of Oil Gaps with High DC Voltage

IEEE Transactions on Power Apparatus and Systems, 1968
The electrical strength of technically clean insulating oil in a direct voltage field is lower when the high-voltage electrode is sharper and of positive polarity. In a uniform field, with distances up to 100 mm, approximately 30 percent lower withstand values are obtained with direct voltages than with alternating voltages (rms values); this is also ...

Breakdown voltage and transition zone of concrete

Cement and Concrete Research, 2000
The breakdown voltage test shows that the weakest pathway of the concrete is the interface of paste/aggregate, i.e., the transition zone. This is also a special proof for the critical voltage of concrete (CVC) test.

The breakdown voltage of silicon dioxide breakdown detectors for fission fragments

Nuclear Instruments and Methods in Physics Research, 1981
Abstract The breakdown of an insulator induced by the passage of a fission fragment takes place at a lower voltage than breakdown due to the application of an electric field only. Breakdown induced by a fission fragment can be interpreted as a two-step process. The first step, of duration tf, is assumed to be very brief.

Breakdown voltages in ceramic capacitors with cracks

IEEE Transactions on Dielectrics and Electrical Insulation, 2012
Breakdown voltages in 27 types of virgin and fractured X7R multilayer ceramic capacitors (MLCC) rated to voltages from 6.3 to 100 V have been measured and analyzed to evaluate the effectiveness of the dielectric withstanding voltage (DWV) testing to screen-out defective parts and get more insight into breakdown specifics of MLCCs with cracks.

High voltage breakdown of titania in vacuo

IEEE Transactions on Electron Devices, 1967
The electrical breakdown of titania in a vacuum using static electric fields is investigated experimentally, by examination of current and temperature variation at different applied voltages. Thermal instability is found to occur at voltages above a critical value.
