Abstract :
THE purpose of this paper is to provide data and from these to draw conclusions on three questions involving the flow of 60-cycle alternating currents in iron or steel structures. First, the paper will attempt to provide a simple empirical means of calculating the a-c impedance of iron or steel members. The application of these data for protective grounding and fault calculations will be presented in a companion paper. Second, the paper will indicate the effect of joints and couplings in iron and steel structures on the flow of 60-cycle currents. The third question that this paper will attempt to answer is what effect the current flow on iron conduit surfaces will have on control conductors in the conduits. The application of these data will also be covered in a companion paper.
