When investigating the effect of the electric rail transport stray currents on a underground metal structure (UMS), as well as calculating the protective devices, one needs characteristics relating their regime parameters to those of traction currents. The mean values of parameters, obtained by averaging the random processes of their changes with relatively short occurrence times, are reduced to some unified base value. Reducing the parameter values is performed when tracing potential diagrams for the rail track or UMS, or when recalculating the drain current into other traction conditions or prospective loads of a traction substation. In other words, one meets a problem that involves modeling the interconnection of the parameters of the "railground-underground structure" (RGUS) with the parameters of the operating regime of a protective device and the traction load.
