Abstract
The process of space charge relaxation in steady flow of dielectric liquid taking into account the fol- lowing electric currents intrinsic conductivity, space charges, convection, and displacement is investigated. It is shown that the area of relaxation is subdivided into two adjacent regions, in which the relaxation processes take place independently, a boundary between these regions moves along the flow with velocity of space charge carriers. Duration of relaxation processes is defined by the time of displacement of the boundary along the whole channel.
