Breakdown in solid dielectrics

Conference on Electrical Insulation & Dielectric Phenomena - Annual Report 1982, 1982
All breakdown in solid dielectrics is ultimately thermal in the sense that the discharge track involves at least the melting and probably the vaporization of the dielectric. In common usage, the classification of a breakdown process as thermal means that it can be satisfactorily explained using reasonable extrapolations of the electrical and thermal ...

Breakdown in a Dielectric Liquid

Nature Physical Science, 1971
WHEN a dielectric liquid is suddenly subjected to a high electric stress, it retains its insulating properties for a certain length of time and then instantaneously (that is, within a nanosecond) becomes a very good conductor when the discharge path is established.

On dielectric breakdown statistics

Journal of Physics D: Applied Physics, 2006
In this paper, we investigate the dielectric breakdown data of some insulating materials and focus on the applicability of the two- and three-parameter Weibull distributions. A new distribution function is also proposed. In order to assess the model distribution's trustworthiness, we employ the Monte Carlo technique and, randomly selecting data-subsets

Dielectric Breakdown in Solid Dielectrics

IEEE Transactions on Electrical Insulation, 1986
A review is presented on Japanese research on the fundamental dielectric breakdown of solid dielectrics. First, the theoretical consideration on the basic breakdown process and the experimental work on pre-breakdown phenomena are described. Secondly, described is the space charge effect on the dielectric breakdown, the importance of which was realized ...

Dielectric breakdown in solids

Digest of Literature on Dielectrics, Volume 41, 1977, 1977
The scope of this chapter is nearly the same as in previous years and concerns the deterioration and breakdown of solid insulation. The deterioration of solid insulation by partial discharges and the phenomena of “treeing” continue to be of great importance to workers in dielectrics research.

Linear dielectric-breakdown electrostatics

Physical Review B, 1988
The dielectric breakdown of solids is a problem of great practical and theoretical interest. It is the electrical analog of the fracture of solids under applied loads. In the case of fracture, the reigning theory for linear elastic materials is linear elastic fracture mechanics.

Dielectric breakdown of solids

Digest of Literature on Dielectrics Volume 42 1978, 1978
In the course of this survey we have consulted more than 60 journals, conference and symposium reports originating from 16 countries. The principal sources of information were the Annual Report — Conference on Electrical Insulation and Dielectric Phenomena, published by the National Academy of Sciences, Washington, D.C., and the publications of IEEE ...

Dielectric Breakdown in Ionic Crystals

Physical Review, 1939
A critical consideration of the theories of dielectric breakdown in ionic crystals proposed by Seeger and Teller and by Fr\"ohlich is given. It is shown that the main difference in the formulae for the breakdown field is due to the fact that Seeger and Teller make the unjustified assumption that an electron transfers energy to the lattice vibration ...

Dielectric breakdown in solids

Digest of Literature on Dielectrics Volume 38 1974, 1974
Breakdown in solids and over surfaces of solids continues to be an area of great technological interest. Understanding has improved in high field conduction of very thin, high-quality films, laser-induced damage, and in aspects of relatively low-field, long-time deterioration of dielectrics.

Dielectric Breakdown in Perspex

IEEE Transactions on Electrical Insulation, 1973
Experiments have been carried out to investigate the breakdown mechanism in Perspex over a temperature range from 20 to 160°C, using impulse voltages of widely differing rise times. The electric strength was found to be sensitive to voltage rise time, reaching a maximum as the rise time is increased, but falling again at longer rise times towards the ...
