Application of the continuous wavelet cross-correlation between pipe-to-soil potential and pipe-to-rail voltage influenced by dynamic stray current from DC train traction
This study interprets results of multiparametric measurements obtained on a pipeline experiencing dynamic stray currents caused by DC train traction. Measurements included three 24 h recordings of pipe-to-soil and rail-to-soil potentials, pipe-to-rail voltages and drainage currents in cases without mitigation measures, with polarized drainage and with forced drainage. Time domain analysis included construction of frequency diagrams and linear correlation between pipe-to-soil potentials and pipe-to-rail voltages. Wavelet space analysis pinpoints time intervals with harmful stray current periods within them and resolves between the dominant potential shifts due to the nearby passing trains and distant trains in the transport network.
