Dielectric strength - Wikipedia

Because dielectric materials usually contain minute defects, the practical dielectric strength will be a fraction of the intrinsic dielectric strength of an ideal, defect-free, material. Dielectric films tend to exhibit greater dielectric strength than thicker samples of the same material.

Dielectric Breakdown Voltage and Dielectric Strength

5.2.2 The dielectric strength of most insulating materials var-ies with temperature and humidity. The test coiditions to be used should be specified in the specification. Usually it is desirable to determine the dielectric behavior of a material over the range of temperature and humidity to which it is likely to be subjected in use.

What is dielectric strength? - Quora

The theoretical dielectric strength of a material is an intrinsic property of the bulk material and is independent of the configuration of the material or the electrodes with which the field is applied. This "intrinsic dielectric strength" corresponds to what would be measured using pure materials under ideal laboratory conditions.

Dielectric constant, power factor, and resistivity of marble

The colored marbles had higher dielectric constants than the white marbles. Also, the moisture affected the dielectric constants of the colored marbles more than it did the dielectric constant of the White Alabama marble. The dielectric constants of the White Vermont and the Blue Vermont were about equally affected by moisture.
