Pantograph-Catenary Arc Detection Technique based on Conducted Effects Measurement on Railway Supply System

This paper focuses on the electric circuit model of the railway supply system and locomotive to analyze the conducted effects of arc events at the sliding contact. The characterization of the arc voltage waveform is backed up by an intense preliminary laboratory activity. The comparison between simulated and measured pantograph voltage and current shows which electric parameters are relevant to identify the characteristic dynamic responses of the system, to use as electric signature of arc events.
