DC RAILWAY LINE VOLTAGE RIPPLE FOR PERIODIC AND A PERIODIC PHENOMENA

Andrea Mariscotti

Abstract

The dc voltage fluctuation (sometimes referred to as ripple) is considered for the pantograph voltage on dc railways. Some indexes and processing techniques are considered to evaluate steady state and transient phenomena: Ripple Index based on time and frequency domain expressions, DFT and wavelet analysis.
