Maintaining the connection with the contact wire is fundamental to the correct functioning of electric railways
Monitoring of interaction forces between the pantograph and overhead line through the use of accelerometers and load cells integrated into the pantograph. In the situation of loss of contact the system would face the interruption of the energy supply and also arcing phenomena leading to deterioration.
Pantograph / Catenary Interaction Measuring System
The Pantograph / Catenary Interaction Measuring System provides both static and dynamic measurements of interaction forces and vertical accelerations, with a dynamic sampling frequency of up to 2 kHz at a maximum measuring speed of 320 km/h. The system can monitor also height and stagger of the catenary wire and measurements can be combined with the other catenary measurement systems.
