Overhead Catenary System (OCS) Inspections

 

AutoCommute has developed an automated system for performing inspections of overhead catenary systems (OCS). Our inspection system can be used to measure:

  • Locations of overhead catenary equipment (wires and support structures)
  • Clearance envelopes (non-catenary structures or obstacles)
  • Overhead catenary properties (wire height, stagger and wear)
  • Pantograph properties (up force on catenary and/or pantograph accelerations)
  • Vehicle properties (location along rail, vehicle speed, heading, acceleration and global position)
  • Visual references obtained during inspections (panoramic view from vehicle, view of pantograph and rail during inspections)
  • Thermography
  • Voltage and current measurements
  • Rail alignment
  • Sensor suite can be adapted based on the needs of the rail system operational or inspection requirements
  • Coming soon: Field service computer that will allow maintenance personnel the ability to quickly locate potential trouble areas based on previous measurements

Inspections can be performed day...

Features

  • Inspection suite is flexible enough to be installed on any type of vehicle
  • Inspections can be performed at any vehicle speed
  • No limit on the number of wires measured or cameras used for recording
  • Measurements can be obtained at up to 50,000 samples per second
  • All measurements and cameras are synchronized
  • All data is presented in an easy to use format


TIS Data Viewing Utility shows data recorded during a typical inspection.  Catenary height, stagger and wear are measured along with vehicle position and visual cues to allow for manual field investigation of potential trouble spots.

Key Benefits

  • Automated inspection system; no need for human inspections on live or in-service catenary lines
  • Determines wire wear continuously along the catenary system (not sparse recordings from each cherry picker location)
  • Automated measurements (no manual recording later transferred to electronic system)
  • Inspections can be performed during revenue service (no need to shut down service for inspections)
  • Sensor suite can verify clearance envelopes on new and expansion lines to verify no outside interference with catenary equipment as well as to verify as-built condition


Inspection equipment is portable and flexible to be installed on any vehicle.
