Breakdown strength of nitrogen at high temperatures
Electrical Engineering, 1961IN A-C circuit-interrupting devices, the post-arc period immediately after current zero is of paramount importance. This period is characterized by the rapid cooling and deionization of the hot gases between the contacts, which build up the dielectric strength of the gap.

Enhancement of breakdown strength of polyetherimide laminates
Proceedings of IEEE Conference on Electrical Insulation and Dielectric Phenomena - (CEIDP '93), 2002The breakdown strength of polymer laminates, polymer base films coated with thin layers of polyvinylidene fluoride (PVDF), was investigated. The PVDF film was coated using a spin coating technique. The DC breakdown strength was studied using an ASTM standard and could be increased by as much as 20% for the polyetherimide laminates.

Size-dependence of the dielectric breakdown strength from nano- to millimeter scale
Journal of the Mechanics and Physics of Solids, 2014 Dielectric breakdown decisively determines the reliability of nano- to centimeter-sized electronic devices and -components. A systematic investigation of the size-dependent dielectric breakdown strength reveals a thickness-independent intrinsic regime ...

IEEE Transactions on Dielectrics and Electrical Insulation, 2011
The aim of this research is to find a way to achieve the epoxy composites with high thermal conductivity and acceptable dielectric breakdown (BD) strength. A value 12.3 W/m·K is the highest thermal conductivity obtained for epoxy composite in Part I.

Solid dielectrics are universally employed throughout the electrical industry as both insulators and charge storage media. Although much research on dielectrics has been aimed at improving insulation for high-voltage equipment in the power industry, there are numerous other applications for which a fundamental understanding of the mechanisms of ...

The breakdown mechanism of poly-p-xylylene film. Prestress effects on the breakdown strength
IEEE Transactions on Dielectrics and Electrical Insulation, 1994Impulse and dc breakdown strengths of 4 /spl mu/m thick poly-p-xylylene (PPX) films were 5.9 and 4.1 MV/cm, respectively. They were independent of temperature in the temperature range from /spl minus/60 to 60/spl deg/C. dc prestressing for a long time (t/sub p/=60 s) reduced impulse breakdown strength for both the same and the opposite polarity. But dc

Dielectric Breakdown Strength of Polyethylene Nanocomposites [PDF]
, 2011 The term “nanometric dielectrics” or simply “nanodielectrics” was introduced in 1994 when Lewis [1] anticipated the potential property changes that would benefit electrical insulation due to nano-sized inclusion. Such materials, containing homogenous dispersion of small amount (normally less than 10wt%) of nanoparticles (with at least one dimension in ...

The breakdown strength of two-layer dielectrics
11th International Symposium on High-Voltage Engineering (ISH 99), 1999In paper the experimental results of the breakdown strength study for the two-layer dielectrics under the high electric field are given. The relation between the breakdown strength (E b ) and the boundary position (ξ) between layers for the two-layer dielectrics is anomalous in character.

On The Breakdown Strength of the Pillbox-Type RF Windows
2007 IEEE International Vacuum Electronics Conference, 2007Comparative research of breakdown powers and their frequency dependences are described in the paper for three types of RF windows. Breakdown power curves are shown to differ significantly from each other depending on the pillbox window design and from threshold power curves of other destructive phenomena.
