DC breakdown strength of crosslinked polyethylene based nanocomposites at different temperatures
IEEE Transactions on Dielectrics and Electrical Insulation, 2020Polyethylene based nanocomposites have been widely researched for being potential insulating materials in high voltage DC equipment. One of their key properties is the enhanced DC breakdown strength (E b-DC ). For a long time, the E b-DC of polyethylene nanocomposites has been attributed to the deep charge traps located at the interphase region ...

Parameters affecting the DC breakdown strength of parylene F thin films
2011 Annual Report Conference on Electrical Insulation and Dielectric Phenomena, 2011The effect of some experimental parameters (electrode area, thickness, temperature and voltage rising rate) on the breakdown strength of films of poly(α,α, α',α'-tetrafluoro-p-xylylene), a fluorinated parylene (PA-F), has been studied.

The experimental study of the DC dielectric breakdown strength in magnetic fluids
Journal of Magnetism and Magnetic Materials, 2004Abstract 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 ...

Space Charge and DC Breakdown Strength of Propylene-ethylene Copolymer/Polypropylene Composite
2021 International Conference on Electrical Materials and Power Equipment (ICEMPE), 2021By blending elastomers, the mechanical properties of polypropylene can be effectively improved then meet the mechanical performance requirements of cable insulation materials. Common elastomer fillers are POE (Polyolefin Elastomer), SBS (Styrene butadiene styrene) and SEBS(Styrene Ethylene Butylene styrene). However, these fillers either have a certain

DC breakdown strength of epoxy-boron nitride nanocomposites: Trend and reproducibility
2015 IEEE Conference on Electrical Insulation and Dielectric Phenomena (CEIDP), 2015In this paper, the results of DC breakdown tests on epoxy - boron nitride nanocomposites are presented. Two different synthesis techniques were used for the composite production and each of them resulted in a different particle distribution. The main goal is to evaluate the reproducibility of the experimental results as it is one of the most important ...

The effect of a floating conductor on the breakdown strength of a DC gap at both polarities
IEEE Power and Energy Society Conference and Exposition in Africa: Intelligent Grid Integration of Renewable Energy Resources (PowerAfrica), 2012This paper presents a preliminary investigation into the effect of a floating conductor on the breakdown strength of a rod-plane gap energised by both positive and negative polarities. This experiment models the scenario of live-line maintenance, therefore providing results for a research into HVDC live-line maintenance, with special reference to the ...

The Dielectric Breakdown Strength of Magnetic Fluids Based on Transformer Oil
Czechoslovak Journal of Physics, 2004The DC dielectric breakdown strength of magnetic fluids based on transformer oil TECHNOL US 4000, with different saturation magnetizations, was investigated in various orientations of external magnetic field. It was shown that the dielectric breakdown strength in H∥E is strongly influenced by the aggregation effects.

IEEE Transactions on Dielectrics and Electrical Insulation, 2014
Dielectric breakdown strength of poly (ethylene-co-butyl acrylate) (EBA) nanocomposites filled with spherical alumina particles was studied as a function of particle coating, moisture content and the effective specific surface area. Two kinds of alumina nanoparticles were used: NA (25 nm in diameter) or ND (45 nm in diameter). The particles were either

Short term DC breakdown strength in epoxy based BN nano- and microcomposites
2010 10th IEEE International Conference on Solid Dielectrics, 2010Nanocomposites have been known in the field of electrical engineering for more than a decade, albeit there are still uncertainties of how the filler properties influence the properties of the composite material. Filler size, shape, aspect ratio and the surface modification, which consequently leads to even dispersion or clusters of particles, are all ...

The role of BaTiO/sub 3/ in modifying the dc breakdown strength of LDPE
IEEE Transactions on Dielectrics and Electrical Insulation, 2000In the present paper, the effect of the addition of fine particles 1%wt BaTiO/sub 3/ to plain low-density polyethylene (LDPE) on the short-term dc breakdown strength of LDPE is investigated. The Weibull plots are used to analyze the breakdown test results.
