[en] The effect of the poloidal field configuration on the operation characteristics of NET is analyzed. To assess the impact of the poloidal field system limits, more than 400 plasma equilibria were computed. The safety factor profiles are reviewed to check the MHD stability of the equilibria. The critical phases of the plasma scenarios where the present limits of the poloidal field are met are found. The fluxes available for the plasma burn are computed. A method to derive the time scale from a sequence of plasma equilibria snapshots is presented. The voltage across the poloidal field coils terminals and the power driven from the network are computed
