When the dielectric constant of a lubricating oil is measured, changes in the dielectric constant of the used oil compared to new oil may indicate the presence of contaminants, such as water or particles, or changes in chemistry of the oil such as additive depletion or oxidation.
256 · The Dielectric Constant, or permittivity - ε - is a dimensionless constant that indicates how easy a material can be polarized by imposition of an electric field on an insulating material. The constant is. the ratio between the actual material ability to carry an alternating current to …
Dielectric Constant of Castor Oil R. Madrak and M. Popovic February 19, 2018 1 Introduction We attempt to measure the dielectric constant of castor oil by various meth-ods, at various frequencies. We used Dow Corning 561 (DC561) silicone transformer oil, Diala AX oil and cured Stycast 2850FT epoxy as 'control' samples with known dielctric .
dielectric constant. However, the dielectric constant in the Debye equation contains a term for the density of the oil, and therefore should show temperature dependence due to changes in the density of the oil with temperature. To a first approximation, the temperature dependence of the dielectric constant of the oil base stock is affected by
Dielectric fluids with higher dielectric constants, such as electrical grade castor oil, are often used in high voltage capacitors to help prevent corona discharge and increase capacitance. Because dielectrics resist the flow of electricity, the surface of a dielectric may retain stranded excess electrical charges.
The dielectric constant, known as the permittivity of a material, is discussed on this page. This property of a material slows down the propagation of light and …

CLIPPER CONTROLS has compiled an extensive list of products with Dielectric Constants. Many of these Dielectric Constants are given at specific temperatures. If your product's temperature is significantly different from those listed there is a good chance that the Dielectric Constant may be different from the values listed.

That is quite small, same order than porous rock, I do not have the number but there are tools which measure the water content of the rock due to the delay of an EM wave because of water higher dielectric constant than anything else (rock, HC).
