METHOD AND SYSTEM FOR MONITORING A PANTOGRAPH OF A RAILWAY VEHICLE AND RAILWAY VEHICLE
First Claim
1. A system for monitoring a pantograph of a railway vehicle, the pantograph being adapted to be connected to a catenary and electrically connected to a traction unit, the catenary being adapted to provide an alternating current to the railway vehicle, the system further comprising:
- a voltage step detection device for detecting a voltage step of a pantograph voltage at the pantograph,qa zero crossing detection device for detecting a zero crossing of a line current, the line current being a portion of a pantograph current provided to the traction unit, the pantograph current being the current flowing through the pantograph; and
a bouncing detection portion adapted to determine at least one bouncing time of the pantograph based on one or more detected voltage steps of the voltage step detection device and/or one or more detected zero crossings of the zero crossing detection device.
