Abstract

The pantograph voltage and current waveforms recorded across the Italian and French high speed railway lines (both Autotransformer 2×25 kV 50 Hz systems) are analyzed to estimate some Power Quality indexes: harmonic spectra, harmonic distortion, displacement factor and fundamental component, in various load conditions. These indexes, that define the electrical interface between the rolling stock and the power supply, are all required by the technical standards for interoperability.
