Clustering techniques applied to a high-speed train’s pantograph–catenary subsystem for electric arc detection and classification [PDF]
, 2016 Assessment of the current collection properties of a pantograph–catenary system mounted on a train is of great importance. Excessive electric arcing can lead to wear of the system’s components, and, at the same time, it can be an index of wear status. In

Assessment of the High-frequency Response in Railway Pantograph-Catenary Interaction Based on Numerical Simulation [PDF]
, 2020 The numerical model is a well-acknowledged tool to evaluate railway pantograph-catenary interaction performance. The current standard restricts most current simulation tools by a cut-off frequency of 20 Hz.

High Voltage, Volume 11, Issue 2, Page 370-384, April 2026.ABSTRACT As the ‘main blood vessel’ of the traction power supply system for high‐speed trains, the ‘wheel‐rail’ coupling grounding reflux system provides the vital channel to send traction current back to terrestrial substations; meanwhile, the rail track also plays a role in transmitting the train's occupancy signal to the control system. An insulated
