Uncertainty of Soil Breakdown Voltage

2010 International Conference on High Voltage Engineering and Application, 2010
Aim of this work is the analysis of the components of uncertainty and the estimation of the uncertainty regarding the determination of the breakdown voltage associated with the soil critical electric field. For that reason, series of measurements have been conducted by inducing impulse voltages to soil samples with different moisture content in order ...

A breakdown voltage doubler for high voltage swing drivers

Proceedings of the IEEE 2004 Custom Integrated Circuits Conference (IEEE Cat. No.04CH37571), 2004
A novel breakdown voltage (BV) doubler is introduced that makes it possible to generate high output voltage swings using transistors with low breakdown voltages. The timing analysis of the stage is used to optimize its dynamic response. A 10 Gb/s optical modulator driver with a differential output voltage swing of 8 V on a 50 /spl Omega/ load was ...

Voltage breakdown characteristics of microwave antennas

IRE International Convention Record, 1959
At low pressures, antennas are susceptible to voltage breakdown. In the case of missiles, for example, there are indications that very low power is sufficient to initiate and maintain breakdown. Since it is essential that the system performance is not interrupted for high-altitude operation, an experimental investigation has been made to study the ...

Effect of Ultraviolet on Breakdown Voltage

Transactions of the American Institute of Electrical Engineers, 1935
The effect of ultraviolet light upon the breakdown voltage of sphere gaps subjected to impulse voltages is considered in this paper. It is shown that, especially for the smaller gaps and corresponding lower voltages, more accurate voltage measurements result when ultraviolet light is used.

Breakdown voltage of high-voltage bipolar transistors

Solid-State Electronics, 1991
Abstract An empirical expression for open-base bulk breakdown voltage of an epitaxial n+pn−n+ bipolar transistor as a function of collector doping density and common-emitter current gain is useful in the design of the collector region of the transistor.

Resistor networks with distributed breakdown voltages

Physical Review A, 1991
As a primitive model for structural breakdown in elastic media, we analyze the failure of random resistor-fuse networks with various distributions of properties. We show that variations in breakdown voltage have a more significant effect than variations in resistance values. This is analogous to the fiuid-displacement problem [D.Y.C. Chan, B. D. Hughes,

Voltage Breakdown in Random Composites

Advanced Engineering Materials, 2003
Voltage breakdown is a strongly localized phenomenon in random‐microstructure composites because the different dielectric constants of metal and polymer matrix turn a uniform external field across the structure into spatially non‐uniform local fields.

An investigation of breakdown voltage in AMTECs

AIP Conference Proceedings, 2002
Experiments are conducted to investigate the DC electrical breakdown voltage in cesium vapor between two planner molybdenum electrodes, 1.6 cm in diameter, separated by a 0.5 mm gap, and relate the results to the potential electrical breakdown on the cathode side of Alkali Metal Thermal-to-Electric Converters (AMTECs).
