Method and measuring device for determining contact wire wear in a traffic engineering system

摘要

The invention relates to a method for determining contact wire wear in a traffic-technical system in which a representative for the wear actual cross-section of the contact wire (4) is determined. In order to provide a cost-effective method, the invention provides that an actual resistance of the section (22) is determined for determining the actual cross-section in a section (22) of the contact wire (4). The invention also relates to a measuring device and a vehicle.
