Nanolaminates: Increasing Dielectric Breakdown Strength of Composites
ACS Applied Materials & Interfaces, 2012Processable, low-cost, high-performance hybrid dielectrics are enablers for a vast array of green technologies, including high-temperature electrical insulation and pulsed power capacitors for all-electric transportation vehicles. Maximizing the dielectric breakdown field (E(BD)), in conjunction with minimization of leakage current, directly impacts ...

Predicting the electrical breakdown strength of elastomers
Extreme Mechanics Letters, 2020Abstract Elastomers have extensive applications in engineering and industrial fields, such as stretchable electronics and soft robotics. Among the various properties of elastomers, electrical breakdown strength strongly affects their application and design due to safety reason. Nevertheless, measuring and determining the electrical breakdown strength

Breakdown strength of impregnated capacitor elements
2016 IEEE International Conference on Dielectrics (ICD), 2016The dielectric strength of unaged and aged capacitor elements is described using a 2-parameters Weibull statistical analysis. The experimental results suggest that aged elements can be split in two populations. The electric stress at the electrode edge is shown to be an important parameter regarding the decrease of dielectric strength.

The breakdown strength of commercial polyethylene
1956 Conference on Electrical Insulation, 1956Most available dielectric strength data for polyethylene apply to laboratory-prepared specimens that have been tested with very special electrodes under highly artificial test conditions. This paper reports certain of the results of extensive impulse tests performed on commercial polyethylene with plane electrodes that approximate the conditions found ...

Oxidation dependence of breakdown strength of XLPE
Conference on Electrical Insulation and Dielectric Phenomena, 2003It has been shown in a previous study (P. Rohl, 1982) that the breakdown strength of polyethylene increases with increasing oxidation levels. The purpose of the research reported here is to verify this somewhat surprising result. Unlike the earlier work, cross-linked polyethylene (XLPE), the principal insulation used in extruded cables, is utilized ...

Breakdown-Strength Enhancement of Coaxial-to-Waveguide Adapters
Journal of Communications Technology and Electronics, 2021An improved structure of a high-power adapter is proposed for broadband matching of coaxial transmission lines and rectangular waveguides with a narrow side wall that are network used in space communication systems. Numerical simulation and optimization of such a microwave two-port are performed with the aid of the finite-element method in a frequency ...

Effect of the insulator size on the breakdown strength
IEEE 1997 Annual Report Conference on Electrical Insulation and Dielectric Phenomena, 2002The effect of the specimen size (S) on the dielectric strength E/sub Bb/ is a well known effect that exists whatever the breakdown type: pure vacuum, flashover, bulk breakdown. Eb varies as S/sup -n/. S can be the insulator surface in case of flashover or the insulator thickness in case of bulk breakdown.

Dielectric breakdown strength in magnetic fluids
physica status solidi (b), 2003AbstractThe application of an external magnetic field on the magnetic fluids induces needle like structuralization of magnetic particles. The influence of this aggregation of magnetic particles in an external magnetic field H on the magneto‐dielectric behaviour and dielectric breakdown strength of a transformer oil based magnetic fluids was measured ...
