IDGC of Siberia - Krasnoyarskenergo PJSCEquipment
- Leica ALS80 LiDAR system,
- Airborne camera,
- Thermal imaging camera.
Deliverable
- Orthophotomosaics on a scale of 1: 2000, image resolution - 10 cm,
- Classified laser reflection point clouds,
- Albums of contact connection thermograms with a unique number of transmission towers,
- Thermographs of inspected components,
- Images taken simultaneously with thermographs,
- Time and coordinates of each survey.
The thermal imaging diagnostics made it possible to obtain the temperature data of the inspected components to detect overheating of contact connections. The thermal imaging survey was carried out simultaneously with the photographic survey of overhead transmission line components, which enabled one to locate the overheating areas.
The thermogram showed a temperature difference of no more than 0.5 ° C.
Project features
The project took place within the framework of the preparation for the XXIX World Winter Universiade 2019 in Krasnoyarsk. The Universiade is a youth analogue of the Olympics, held every two years in different countries of the world. The preparation for this event is as large-scale as the preparation for the adult Olympics. Krasnoyarsk got a win against the Swiss canton of Valais. The Winter Universiade was held in Russia for the first time, considering even the Soviet period. So, the responsibility for the excellent organization thereof was very high.30 sporting venues were reconstructed and rebuilt in the city. To provide the trouble-free power supply to all this complex infrastructure scattered over the area of more than 500 square kilometers, and to minimize the energy losses, it was necessary to examine and upgrade HV power transmission lines. The airborne laser scanning and thermal imaging were recognized as the most effective method of survey.
