Condition Monitoring of Pantograph Contact Strip

• A common issue in electric railway operation is the wearofthepantographcontact strip. This is especially pronounced with ice or rime frost on the overhead line that causes arcing between the contact strip and the contact wire. To monitor the contact strip it is possible to utilise the fact that arcing between the contact strip and the overhead line generates a DC component in the AC locomotive current. The paper presents a method forconditionbased maintenanceofthe contact strip. The wearofthe contact strip is predicted bymonitoringthe running distanceofthepantographas well as the DC componentofthe locomotive current. To evaluate the method, measurements have been carried out on a Swedish Re locomotive during winterconditions.
