Study on Improvements to the Dielectric Breakdown Strength of Extruded Dielectric Cables

IEEE Transactions on Power Apparatus and Systems, 1985
This report relates to the study on insulation materials for obtaining extruded dielectric cables with high dielectric breakdown strength. Firstly, the dielectric breakdown strength (EB) of a variety of plastics was evaluated by the use of recessed sheet samples. As a result, the EB for high density polyethylene (HDPE) proved favorable.

Breakdown strength of solid dielectrics in liquid nitrogen

IEEE Transactions on Dielectrics and Electrical Insulation, 2008
The objective of this research was to determine if a relationship could be found between dielectric strength and other properties of electrical insulating materials in the medium of liquid nitrogen on an empirical basis by using variables predicted by basic theory.

Dielectric breakdown strength of mineral oil based nanofluids

2016 International Conference on Condition Monitoring and Diagnosis (CMD), 2016
In this paper, the dielectric properties of the mineral oil-based nanofluids was studied. The aim of this research is to improve electrical property of the mineral oil by applying nanotechnology knowledge. Three types of nanoparticle i.e. Titanium dioxide (TiO 2 ), Barium titanate (BaTiO 3 ) and Zinc oxide (ZnO) with the mean diameter less than 100 nm ...

On why dielectric breakdown strength reduces with dielectric thickness

2016 IEEE International Reliability Physics Symposium (IRPS), 2016
An intrinsic/fundamental-physics reason is presented for why the dielectric breakdown strength Ebd reduces with dielectric thickness tdiel. Through extensive use of layered dipole summations, it is shown that the Lorentz factor L tends to increase with thickness.

The breakdown strength of two-layer dielectrics

11th International Symposium on High-Voltage Engineering (ISH 99), 1999
In 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.

Effect of Elongation on Dielectric Breakdown Strength in Polyethylene

Japanese Journal of Applied Physics, 1975
A measurement of the dielectric breakdown strength in low- and high-density polyethylene was carried out under the condition of elongation by tensile stress. The wave forms of applied voltages were a.c., d.c. and impulse (1×40 µs) voltages, and the thickness of films of polyethylene was ca. 50 µm.

Increased dielectric breakdown strengths of melt-extruded polypropylene films

Polymer, 1993
Abstract Melt-extruded polypropylene resin containing 1% or 2% ceresine wax yielded thin films that had significantly increased dielectric breakdown strengths but with virtually identical bulk dielectric properties. Ceresine wax acts as a trapping centre for electrons and by minimizing ionization of host polypropylene molecules, dielectric breakdown ...

Remarkable Dielectric Breakdown Strength of Printable Polyelectrolyte Photopolymer Complexes

ACS Macro Letters
Polymer-based dielectrics are struggling to keep pace with the increasing demands of modern electronics. This lag in dielectric performance has spurred significant interest in the production of advanced dielectrics via novel chemistries and processing techniques.

Dielectric Permittivity and Breakdown Strength of Molybdenum Trioxide Films

Journal of the Physical Society of Japan, 1975
Dielectric behaviour of molybdenum trioxide films as a function of frequency (up to 10 MHz), thickness (from nearly 350 to 5000A) and temperature (room temperature to nearly 200°C) is reported. The films were prepared by vacuum evaporation technique and their thickness was measured by multiple beam interferometry.

MATCHING MATRIX AND FILLER DIELECTRIC CONSTANTS TO INCREASE DIELECTRIC BREAKDOWN STRENGTH

2013
Dielectric breakdown strength increases by matching dielectric constant values at the composite interface. Cyanate ester resin is modified with BaTiO3 nano-powder to match E-glass dielectric constant.
