Paulius Kalmantas, director of public relations projects at Energijos Skirstymo Operatorius (ESO), a news portal lrytas.lt They reported that this technology is theirs, and the helicopter is doing its job – inspecting the power grids. A special radar inspects overhead power lines that are difficult to reach.
In order to accurately and efficiently assess the most threatened vegetation and protect non-hazardous trees, ESO uses innovative aerial inspection methods using LiDAR (light and range detection) technology.
The scan from above collects a huge amount of information that is then processed, classifies the detected objects, identifies the vegetation and the airlines themselves. Thanks to smart inspection, it is possible to accurately identify the most dangerous trees and even their heights, making it possible to objectively identify which trees pose the greatest threat.
“We decided to increase the scope of smart airline inspections and in the near future to additionally scan and photograph around 8 thousand. km of power lines. We look forward to expediting airline defects and inspections in this way.
By inspecting the line elements from above, it is possible to more accurately identify damaged insulators or cables and thus prevent future failures. The photos also provide accurate measurements of the airlines themselves; this data provides an opportunity to compare and find discrepancies in the systems, ”said Karolis Gesevičius, an innovation expert at ESO’s Service Development Service.
The director of ESO’s public relations project said the technology was tested last year: 1,000 people were inspected. km of airlines: “The number is small because I wanted to see what the value of this information is.
Seeing the benefits of this technology, we signed a two-year contract, during which about 8 thousand people will be inspected. km of airlines – 3 thousand. this year and 5 thousand. next year. “The interlocutor emphasized that this contract is made to order.
“We tell you where we want to fly, and our partners fly there and see everything. It is possible that those 8 thousand. The kilometers will not be exhausted. Our partners use a helicopter and several drones. A radar is installed in drones or helicopters, which collects data ”Said P. Kalmantas.
Greater precision
LiDAR and aerial defect capabilities provide much higher data accuracy, much more accurate than the current process of ESO inspection team engineers traveling to designated locations and inspecting power lines live.
From the digital data it is possible to complement and refine the information of the network data in the information systems, and by accumulating a file of said data, it will be possible to carry out a vegetation forecast and maintenance planning.
“However, new technologies do not completely change the existing fault process, because we cannot inspect the condition or the interior condition of the transformer, substations, isolators, the underside of the supports and the structures of the network. Therefore, the LiDAR process complements the current defect process, but we cannot fully realize the defect without human intervention.
The biggest benefit of the latest technology is saving staff time, which can be used for other tasks designed to ensure network reliability, ”said Egidijus Šatrauskas, Director of the Department of Network Data Management.
