3. Permittivity and dielectric losses in solid insulators
3.1 Definitions and meaning of permittivity and dielectric losses
In the (purely theoretical) case of a perfect dielectric, the relative permittivity ε
r
is defined as the ratio between the capacitance C
x
of a system of electrodes immersed in the dielectric and the capacitance C
v
of the same electrode configuration in a vacuum :
