During day-to-day operations, defective overhead wiring can gradually cause wear and tear on passing pantographs, meaning the units themselves begin to degrade and inflict further damage back to the wires.

The result is an increased risk of dewirements, costly delays and reduced fleet availability.

However, locating the defective sections one OHW can be time consuming and challenging,with repair work often undertaken only after failures have been reported.

Introducing CatMon

CatMon is a technology from Ricardo that monitors the interface between the OHW and the pantograph unit to provide real-time intelligence of emerging faults across the network.

CatMon uses two accelerometers mounted to a pantograph head to detect defective OHW components and report the time and location via 3G to a cloud hosted server.

The data is analysed on the server and reported to maintenance teams through a web-based interface, or the operator's own systems.

Reports and diagnostics

The user interface allows operators to identify problems with the overhead wiring in the network so that trends can be monitored and appropriate responses planned.

Key characteristics

  • All hardware is securely installed to the pantograph with no impact to the vehicle - installation time is around one hour.
  • Power is provided by solar and battery, with communication via 3G.
  • Continuous monitoring using timetabled train services eliminates the expense and disruption of a measurements train or visual inspection.
  • Minimal maintenance required for the units.
  • Supported by Ricardo's in-depth knowledge of rolling stock and infrastructure maintenance.
