After the opening of the Lantau and Airport Railway (LAR) in 1998, the dynamic performance of the Overhead Conductor System (OCS) was considered needing improvement. There were scintillation, broken droppers and excessive worn-out of contact wire and high consumption of pantograph collector strips. The maintainers had limited number of suitable measuring devices and analytical tools at their disposal...
Modern electric trains in metro systems collect energy along the route for on-board utilization. If the overhead conductor system (OCS) is used to transmit the electric energy, then the interaction of pantograph strip on contact wire will form a wear couple that is continuous throughout the railway network. Unlike the replacement of pantograph strips that can be done off-site in depots, the renewal...
