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 ...

Magneto-fibrillation augments the breakdown strength of ferrofluid dielectrics

Journal of Applied Physics, 2020
The present article reports experimental evidence with a theoretical formalism on the enhancement of the dielectric breakdown strength of ferrofluids by inducing magneto-fibrillation with an external magnetic field. The dielectric breakdown strengths of oil based ferrofluids are determined, and it is further shown that the strength enhances due to the ...

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.

Enhancement of Dielectric Breakdown Strengths in Polymer Film Capacitors

SAE Technical Paper Series, 1992
<div class="htmlview paragraph">Breakdown voltages of wound, polymer film/metal foil capacitors have been dramatically increased by briefly exposing them (after they had been spirally wound) to a low pressure, low temperature gas plasma. Exposure of wound, polycarbonate-based capacitors to a 96%CF₄/4%O<sub>2</sub ...

Effect of temperature on the electric breakdown strength of dielectric elastomer

SPIE Proceedings, 2014
DE (dielectric elastomer) is one of the most promising artificial muscle materials for its large strain over 100% under driving voltage. However, to date, dielectric elastomer actuators (DEAs) are prone to failure due to the temperature-dependent electric breakdown. Previously studies had shown that the electrical breakdown strength was mainly related

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.

Frequency dependence of the electric strength of dielectrics in electrical breakdown

Glass and Ceramics, 2006
It was shown that the dependence of the electric strength of solid dielectrics on the frequency is determined by the corresponding dependence of the dielectric constant and it decreases sharply in the region of dispersion frequencies in elastic oscillations and on relaxation oscillators (in the condition ω0 = 1/τ) in relaxation oscillations.

Structure and dielectric breakdown strength of nano calcium carbonate/polypropylene composites

Journal of Applied Polymer Science, 2013
ABSTRACTNanodielectrics, a 21st‐century phenomena, is envisioned to be the answer for material challenges in progressive high‐voltage technology. It is well known that the proper dispersion of nanoparticles plays a key role in improving the dielectric properties of a material, but to understand where changes in the properties of a material originate ...

The experimental study of the DC dielectric breakdown strength in magnetic fluids

Journal of Magnetism and Magnetic Materials, 2004
Abstract Magnetic fluids have been studied for use as a high-voltage insulation. High-voltage measurements on magnetic fluids based on transformer oil, as a function of volume concentrations of magnetite particles and applied magnetic field, showed the increase of the DC dielectric breakdown strength opposite transformer oil, if the saturation ...
