Inthis workwe optimize the neutral reactorvalue in orderto minimize the secondary arc current in transmission systems with shunt reactive compensation. Sensitivity analysis was conducted to identify neutral reactor values that will promote high probability of self-extinction the secondary arc current in different transmission systems to ensure a success single-phase opening/reclosure maneuver. The method is presented to identify the optimum neutral reactor and also values of the secondary arc current for typical lines of Brazilian system.
