Constrained decision planning applied to field profile optimization in LPS of structures directly struck by lightning

The search for the best configuration of the lightning protection system (LPS) that maximizes the regions inside the building, in which the values of the field are less than the specified threshold levels is an important topic of the LPS design. In this paper, we propose the use of a constrained decision planning tool to optimize the field profile in the regions where the high susceptible equipment will be placed. The induced magnetic flux is evaluated by time-domain simulation. The concepts of "safe area" and "connectivity index" are presented and used as measures of this procedure.
