The Influence of the Cathode Material on Measured Breakdown Strengths of Solid and Liquid Dielectrics [PDF]

open access: yesAustralian Journal of Physics, 1954
An outline is given of a general method of accounting for the effect of electronic and ionic space charge in the breakdown of solid and liquid dielectrics. Detailed calculations are performed for a special model of both a liquid and a solid dielectric, and the results are compared with recent experimental work.

Dielectric Breakdown Strength of Thermally Sprayed Ceramic Coatings: Effects of Different Test Arrangements

open access: yesJournal of Thermal Spray Technology, 2015
Dielectric properties (e.g., DC resistivity and dielectric breakdown strength) of insulating thermally sprayed ceramic coatings differ depending on the form of electrical stress, ambient conditions, and aging of the coating, however, the test arrangements may also have a remarkable effect on the properties. In this paper, the breakdown strength of high

The effects of crosslinking byproducts on the electrical properties of low density polyethylene

open access: yes, 2011
Crosslinked polyethylene (XLPE) is widely used for high voltage insulation in power transmission systems. However, it has been found that, after crosslinking with Dicumyl Peroxide (DCP), the crosslinking byproducts such as acetophenone, ?-methylstyrene ...

Designing Strong, Tough, Fire‐Retardant and Self‐Healing Elastomers with Phosphorus/Nitrogen‐ and Biphenyl‐Containing Segments

open access: yesAdvanced Materials, EarlyView.
By designing a P/N‐ and π–π interacting biphenyl‐containing diol as hard segments but side groups, a strong, tough, fire‐extinguishing and self‐healing elastomer is developed, demonstrating a break strain of ∼2500%, a toughness of 379 MJ/m3 and a tensile strength of 46 MPa, as well as a healing efficiency of 95% (tensile strength) and 99% (break strain)

Size-dependence of the dielectric breakdown strength from nano- to millimeter scale

open access: yes, 2013
Dielectric breakdown decisively determines the reliability of nano- to centimeter sized electronic devices and components. Nevertheless, a systematic investigation of this phenomenon over the relevant lengths scales and materials classes is still missing.
