Testconsult has just completed trials of its TDR2 and BGCMap systems for Hungarian utility company Mavir and local consultant Energin to prove the potential of the systems to quickly assess tower foundations.
According to Testconsult, the systems are ideal for the application as the equipment is lightweight and portable, and can all be carried by one field engineer, with testing taking less than 20 minutes at each tower.
The BGCMap system provides a rapid means of determining high risk tower foundations, by using LPR methods to check rate of corrosion and can be used to establish an on-going inspection regime.
The system has in-built GPS, so test data can be accurately related to field location. The TDR2 system was used to confirm the foundation depth and the presence - or in some cases, not - of enlarged bases.
The trial in Hungary was carried out on a section of power line to the south west of Budapest.
