Transitions Maps for Integrity in Operational Procedures of Electrical Installations

The design of a power system involves assessment of safety and functional performances of the installation that can be corrected and perfected during its life cycle with risk and quality management. The design has to be comprehensive and adaptable during the overall operational life cycle of the system, looking for the best methodologies and the most complete information. Safety configurations and accurate plans allow a guaranteed risk reduction so that in contingencies a competent operator can operate the power system properly. The authors suggest transitions maps for assisting the elaboration of the procedures from a set of a power system to another one and for helping the training of operators. In human reasoning and multi-modal information processing, the diagrams offer a visual clarity in examining spatial constraints and in recognizing correct inferences. The transitions maps extend the Euler-Venn diagrams and concur to an explanation of the four-color theorem.
