One-line diagrams are widely used to represent the electrical power system current state and its probable performance in the case of studies and simulations. Hence, its adequate construction is of great importance to avoid inaccurate decisions of the network operators. In order to reduce the human elimination of superpositions of buses. The approach was successfully tested with the Institute of Electrical and Electronics Engineers (IEEE) 30 buses standard system and with a portion of the Brazilian network.
