Surveying in the transformer substations prepares and supports design planning, execution and control and monitoring jobs.
When the most demanding accuracy is called for to set up and adjust machines, the laser tracker is employed. The laser tracker functions directly in the part coordinate system and immediately indicates deviations.
Settling of structures or structural components can, for example, result from deformations of the subsoil as a consequence of load input or vibrations. Settling or position monitoring measurements are capable of detecting the changes at an early stage. The building operator can then quickly implement countermeasures.
Surveying the tracks and, if required, the carrier wheels allows the documentation of crane track wear and the issuing of warnings in case of excessive wear. The result is in the form of a report with the standard values at each setting point for adjusting the tracks.
Here the choice of measuring method depends on the required accuracy and the dimensions of the component. The axes or dimensions are determined by high-precision surveying in 3D and transmitted to the construction CAD.
Motion of the plant results in wear and causes changes in the corresponding geometry. These deformations can be detected down to 0.02 mm and the deviations from the required values documented. Deviations can be recognized already before integration.
No plant remains as originally planned and built!
The as-built acquisition is therefore increasingly important for replanning the existing facility.
This is the basis for the planning of rebuilding and supplementary measures, failure simulation or the planning of alternative production flows.
The contact-free measurement method and the variable distances from the facility enable the measurement campaign to take place without greater disturbances of the work flow. The measured data can be entered in the usual CAD data formats and processed further.
Following 3D laser scanning a highly accurate 3D model is available as a point cloud of the original.
For further processing in the CAD, however, mostly surfaces are required. Here discrete surface reconstruction is an important method. This results in a CAD model with the least deviations from the original.
With 3D modeling all relevant objects are stored with their geometry and factual data to a database. The 3D models correspond to the technical and content-oriented requirements of virtual plant planning. Collison tests of the different subsections with each other and with the building support efficient planning.
This results in process reliability!
