As-built documentation in electrification projects using tCat: a race against the laser gauge
In an OLE system, the catenary runs in a predefined path above the track in order to guarantee good electrical contact with the pantograph as well as minimize wearing.
Before the authority performs his own OLE tests or the system is commissioned it is often required and a good practice activity for the catenary installer to check the geometry of the contact wire and hand over to his client an as-built report reflecting the height and stagger of the contact wire at the masts and the midspans.
Producing a height and stagger report is a straightforward procedure using the tCat:
- Locate the tCat trolley at a mast and enter an initial stationing and/or mast ID#
- Click on “measure”
- Move towards the next mast, at walking speed, stop at the midspan and click on “measure”
- Move towards the mast and click on measure. Enter any singular point or element that you want to populate the database with.
- Rinse and repeat!
Benefits from using tCat
No need to carry the laser rule on your back, no need to spend time looking for the contact wire at each measurement, no need to write down the reading on a notebook, no need to enter your notes on a spreadsheet.
The tCat will do it all for you automatically, you get your report from the field, just seconds after you are finished.
The recorded data can be exported to different formats like .csv and excel.
