Despite rigid strength, energy infrastructure facilities require maintenance and care. Their effective operation directly depends on relevance and completeness of information about state of the power stations, PTL and heat mains. Today, use of the traditional surface methods of the utility networks is not the cheapest and the most effective method of such information collection.

Examination of any facilities will be much cheaper and less labor-consuming when you start to apply air mapping technologies by Geoscan. Our systems perfectly manage to generate maps and 3D models. Unique opportunities of UAV will allow you to inspect the equipment without shut-down and reduce troubleshooting time without costly downtime of the PTL.

PTL inspection

Remote monitoring of power transmission lines from UAV significantly reduces time and risks upon field works performance. Technology of contiguous objects survey developed by Geoscan specialists allows to shoot up to 200 km of PTL per day. Along with that, flights are performed at a safe distance from the supports and cables and do not require voltage tripping. Survey results will enable you to determine condition of support elements, detect damaged insulators, poles and attachment units. Moreover, energy workers will be able to assess natural factors impact, determine deviations of wires and insulation condition from the acceptable standards. Thermographic examination will ensure manifestation of hidden defects and abnormal modes of equipment operation.

Heating main inspection

Aerial survey is rightfully considered to be the most effective and efficient method of heat mains monitoring. Application of unmanned aerial vehicles brings such effectiveness to a new level. UAV application is incomparably cheaper than the piloted aviation. Detailed photos in the visible range allow to view defects of the insulation layer and signs of corrosion. Thermal survey provides search for heat mains defects at the initial stage and leaks on the underground sections of the heat mains. Heat mains defect discovered in proper time will not become the reason of severe emergency, and you will be able to avoid high expenses for repair works.

Renewable energy infrastructure inspection

Using Geoscan UAV, you can examine wind-powered generators effectively and control their condition. Discovering damages at the most initial stages, you will avoid losses from unexpected breakdowns or expensive repair in case of severe emergency. Modern solar panels are notable for their high reliability. However, sometimes they go out of service. Infra-red band survey can detect faulty elements quickly and at a low cost. Timely replacement of such panels will ensure continuous operation with maximum performance for the solar power station.

Local facilities inspection

Facilities, such as dikes and dams, cooling towers and chimneys require regular inspection and condition control. Goescan UAV can assist in performance of such routine works. Monitoring of hard-to-reach structures, registration of their state, detection of damages and deformations becomes much easier when you have an UAV. You can examine facilities from all sides without shutting down their operation, erection of stages or exposure people to unnecessary risk. High-quality of the photos, video and thermal survey enables engineers to determine sites requiring maintenance in a prompt manner.

Emergency response

Accurate assessment of damages is critical upon planning of works on heat- and power-supply recovery. Data obtained with the help of UAV will help to solve different tasks – from searching of the emergency place to damage evaluation in case of natural disasters. Roads blocked by the fallen trees, snow or landfalls will not impede detection of damages. Information about emergency in the real time will ensure rapid decision-making. Our unique equipment together with our experience and knowledge of your specialists will allow to determine priorities correctly and promptly send the emergency teams. Accurate faults isolation allows to reduce elevated works to the minimum extent, minimize works in the high-voltage areas and reduce the number of the field visits.

Modeling and analysis

Our specialists developed spatial analysis tools for the monitoring and maintenance of PTL. GIS Sputnik tools allow to model supports position and recover wires trajectories. With the help of such models, you will be able to determine automatically the area of forest coverage within the spans, calculate crowns and detect zones of potential trees falling. Moreover, it is also possible to determine the deflection amount and even cubic capacity of wood on the site of concern. Our software will not only calculate the required indicators but will also display the results in a convenient format.


Results of processing of Geoscan UAV survey data include high-resolution photos, orthophotomap and digital model of the area. By using these materials, it is possible to determine plane coordinates and heights of PTL supports above the sea level. You can also make topographic and thematic maps. Such basis will be useful upon designing new routes of PTL and heat mains, reconstruction and construction of the facilities, determination of the most suitable access roads.
