Voltage Breakdown in Random Composites
Advanced Engineering Materials, 2003Voltage breakdown is a strongly localized phenomenon in randomâmicrostructure composites because the different dielectric constants of metal and polymer matrix turn a uniform external field across the structure into spatially nonâuniform local fields.

An investigation of breakdown voltage in AMTECs
AIP Conference Proceedings, 2002Experiments 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).

Effect of total voltage on breakdown in vacuum
Electrical Engineering, 1935The 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 ...

Uncertainty of Soil Breakdown Voltage
2010 International Conference on High Voltage Engineering and Application, 2010Aim 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 ...

Empirical model of MOSFET breakdown voltages
IEEE Transactions on Computer-Aided Design of Integrated Circuits and Systems, 1993An additive model of drain-to-source current of a MOS transistor in the breakdown region is presented for the circuit-simulation SPICE program. An additional drain-to-source current is described by mixed quadratic and exponential formulas. Continuity of current and its first derivatives is assured.

1967
Abstract : The analysis of the results of the preliminary experimental program has been pursued with emphasis on the visible radiation from vacuum gaps. The results are consistent with both thermal and transition radiation phenomena. The 320 kv system has been assembled and the components necessary for the pilot experiment checked out, viz.

High voltage subnanosecond breakdown
IEEE Transactions on Plasma Science, 1998Present-day ultra-wideband radiation sources produce Megavolt pulses at hundreds of picosecond (ps) risetimes. Empirical data on the breakdown characteristics for dielectric media at these short time lengths and high voltages are either extremely limited or nonexistent.

LTCC Breakdown Voltage Investigation
Additional Conferences (Device Packaging, HiTEC, HiTEN, and CICMT), 2016Abstract High voltage properties of the LTCC (Low Temperature Co-Fired Ceramics) cofired ceramic tape are presented. Chauvin Arnoux C.A. 6555 insulation tester is used to measure the leakage current and the resistance. Measurement is possible up to 15 kV. The DuPont 951 test structures are manufactured.

Statistical inferences for breakdown voltages
IEEE Transactions on Dielectrics and Electrical Insulation, 2000This paper examines some analysis of breakdown voltages, and gives diagrams and arguments to support re-analysis of the relevant data sets, again using the three parameter Weibull distribution. The paper shows that graphical means provide a useful method for examining the log-likelihood of data, particularly when careful examination of this function is
