Building structures are systems of connected parts designed to support continuous persons’ occupancy. The safety of persons against electrical indirect contact under ground-fault con- ditions depends on the potential gradient established by the fault current within the structure. In buildings, persons are in contact not only with floors but also with walls and/or conductive objects; thus, ground-fault potentials depend not only on the configuration and location of the grounding system with respect to the point of touch but also on the construction type of the structure as well as on the floor material. In this paper, through both analytical models and field measurements involving different types of buildings (i.e., masonry and reinforced concrete), the authors have investigated the main factors that affect the distribution of ground potentials in structures.
