General system of equations of electrostatic field in the weakly conducting dielectric liquid in the interelectrode gap of a plane-parallel capacitor is formulated. Main equation for distribution of electric fields intensity is obtained and similarity criteria for the processes of current conducting and charge formation are found. On the basis of the analysis of signs of the first and second derivatives of electric field intensity the conditions of arising some or other field distribution are established In particular, it is shown that in the con- ditions of “pure” polarization (current is zero) bipolar structures are impossible. On the contrary, their ap- pearance is connected with the passing of enough strong current. Ways of the main equation solving are de- veloped. Approximate solution for the general case of the problem setup is given.
