A Rate Type Constitutive Equation for the Description of the Corona Effect

A rate type model for the description of the corona effect is proposed. It includes the relaxation properties of an electric line due to the presence of the corona effect. Any perturbation propagates with a constant speed-a characteristic of the line. The constants of the model may be determined from the experimental data [1,2,3]. The model may be used to study wave attenuation due to corona discharges. This attenuation is caused by both the electric "viscosity" of the dielectric and the tail of the wave.
