Dielectric spectroscopy; dielectric spectroscopy
Technique for measuring the complex impedance of an electrical insulator as a function of frequency, and deducing its permittivity, resistivity and dissipation factor.
Permittivité réelle et imaginaire ; imaginary and real permittivity
The real component ε' is none other than the relative permittivity ε r ; it represents (give or take a constant) the "susceptibility" of a dielectric to polarize under the effect of an electric field. The imaginary component ε" is known as the relative loss index, because it allows us to find the active power P a dissipated by the capacitor.
Conductivité AC/DC ; ac/dc conductivity
