Abstract :
Transient effects in electrical railway networks exhibit frequency variations due to nonlinearities in an otherwise approximately linear system. These effects cannot be analyzed by either pure time-or frequency-domain analysis, but a mixed time-frequency analysis using wavelets is found particularly suitable in two practical application examples
