According to the safety standards for railway transport, the effective amplitude of the traction amperage harmonic with frequencies of 25 Hz and 50 Hz should not exceed 1 A if the effect is continuous (for over 0.3 s) and 11.4 A if the effect has a pulse character (continues for less than 0.3 s). A circuit design is proposed and the possibilities for incorporation of an input double-notch low-frequency ripple filter are considered. Recommendations regarding the use of mathematical models for the calculation of transient processes in a DC electric-traction network are given. An analysis of the simulation of processes in a low-frequency filter shows that the emission of interference by the electric rolling stock should be estimated using the wavelet analysis since this approach best suits the studies of non-stationary signals.
