Abstract
Current collection is a key issue in modern electrical railway, and its performances are mainly determined by the pantograph/catenary interactions. Whilst being the less investigated topic, the pantograph/catenary mechanical interface is the most crucial one. Many incidents and traffic interruptions are due to degraded, or even damaged, electrical contacts between current collectors and contact wires. During the 6th European Framework Program (FP6) CATIEMON project (CATenary InterfacE MONitoring), both FBG-based sensors and systems dedicated to the pantograph/catenary interaction monitoring - directly from the high voltage contact wire - have been developed and tested. This paper describes their design and installation but also results coming from field-tests. It highlights their advantages for the railway stakeholders and end-users in term of train operation enhancement.
