For development of calculation method of electrical parameters of interleaved out current lead there is was performed numerical simulation of electromagnetic field of buses while variation of design parameters and way of conductors interleaving in order to find their active and inductive resistances. The simulation results on the one hand are conformed qualitatively and quantitatively to conventional method, and on the other hand have proved necessity of more carefully calculation of active resistance, thus it commensurable with inductive one for wide range design parameters. The results of the investigation can be approximated by closed formulae which allow calculate active and inductive resistances of interleaved bus package precisely and simply. The formulae considerably simplify process of multivariate calculation of electrical parameters of this partition of current lead to equalize impedances of bus packages of different phases by means of changing of interleaving way, of number and dimensions of conductors and distances between them.
