The random nature of stray currents leaking from d.c. electric tractions in urban agglomerations imposes that the changes in polarization of underground metallic structures, and in any other measurable electric quantity, connected with the stray current flow must be treated as stochastic processes. The above changes should be evaluated according to the rules of analysis of random signals. The paper describes the practical application of computer-aided technique for the measurement and analysis of stray current corrosion activity and effectiveness of protection measures on underground structures.
