During the operation of EHV lines, the overwhelming proportions of single-phase short circuits can be eliminated in the cycle of a short-term no-current pause, followed by the restoration of the normal circuit. Thus, SPAR refers to the most important measure that increases the reliability of EHV power transmission. The success of elimination of arc short circuits in the SPAR cycle on the one hand, are determined by the characteristics of the secondary arc arising in long air gaps, and on the other hand - the effectiveness of used on lines of methods for reducing secondary arc currents and recovering stresses in the place of arc burning after its extinction. Implementation of SPAR is difficult the presence of recharge of the short circuit from the side of the non-disconnected phases. The paper shows how by proper adjustment of the operating parameters that determine the conditions for extinguishing the secondary arc we get an additional reduction in losses in the transmission line due to more accurate compensation of charging power.
