- Abstract
In a polar dielectric occurring under the conditions of large electrothermal loads, it is necessary to take into account the temperature dependence of the conductivity γ(T) and complex permittivity ∈(T). An allowance for this circumstance in the simplest model of the Debye relaxation polarization leads to deviation of the ∈' =f(∈') curve from the well-known Cole-Cole semicircle. Exact solutions of the model problems for a flat capacitor are presented for the cases when the temperature gradient is caused by an external source and by relaxation losses in the dielectric material.
