Pantograph wear assesment in overhead conductor rail systems [PDF]
, 2011 Wear is the phenomenon that determines the lifetime of the collector strips. Since wear is an inevitable effect on pantograph-catenary systems, it is necessary to determine optimal operating conditions that can mitigate its effects. In this study we have

Real-time condition monitoring approach of pantograph-catenary system using FPGA
2016 IEEE 14th International Conference on Industrial Informatics (INDIN), 2016 In recent years, the importance of railway transport increases with the development of fast trains. Maintenance of this train should be performed at an early stage for safety and reliability. Because pantograph-catenary system is used to transmit the energy to the train in most of the electric trains, the early detection of the problems occurred in ...
